After months of crochet, I have finally finished the 336 granny square blanket. First of all, before I am able to share the blanket’s pattern (updated) (~~pattern to follow soon~~), I would like to share with you on how many non-repetitive color combination of granny squares you can obtain out of a number of yarn colors. I used this blanket’s granny square as an example to explain but you can easily apply your design into it. The complete blanket is using 8 colors and 1 white to crochet.

If you have studied statistic and algebra in mathematics, you probably came across some formulas of the probability in Permutations (nPr) and Combinations (nCr) of a set of number. Don’t worry about the formulas, I am not going to be the mathematics teacher today and I am not going to teach you how to apply the formulas to get the number of colors combination and sequence for your granny squares. Instead, I will show you a few charts and how to adapt your number of yarn color for your granny squares. You can see the answer immediately of how many unique squares you will get based of the numbers of the color of your choice. After that, you will see how to combine your colors to make up the numbers as shown in the chart.

I have spent many hours on figuring out how to make this technique straightforward and easy to tailor into your project. I hope this could save up your time so that you could do more crochet instead of cracking the numbers.

## Granny Square Colors Combination

**[Update: the pattern of the completed blanket is here]**

As introduced in the first page, I am going to use this tricolor granny square to explain how many unique squares you will get out of 8 different yarn colors. These squares are crocheted in a white border with a tricolor circle in it. Since the white appears in all squares, it is not counted as one of the colors. In order to make it easy to understand, I have prepared some charts for you to refer to while I explained how to use them. Please read through the instruction, understand it and you will be able to apply your number into the technique.

### Total Granny Squares – Quick Reference Chart

This chart shows you the total number of unique color granny squares you can crochet based on the number of yarn colors use (peach color bar) versus the amount of color appear in 1 granny square (blue color bar).

An example: If you have 8 yarn colors and you want to use 3 colors for 1 square, the chart says you will get 336 of unique squares. You have 56 different color combinations and each color combination will give 6 different sets of sequence in the color order, 56 x 6 = 336, this is how it makes up to 336 unique square that none of them are identical.

This is a quick reference chart so that you can quickly know how many colors you will need to use to make the number of unique squares for your project. After knowing the number, next, you will need to know how to get the sets of color.

### Color Combination

Before you start to combine the color, mark the numbers on your yarn label with 1,2,3,4,…. this will make it easy for reference when you read the charts below.

Based on the example above where you have 8 color yarns and use only 3 colors in 1 square, follow the chart’s color number to systematically pick up all the 56 color combinations.

Start from top right and going down, the first one is color 123. Change 1 color at a time to obtain to the new color combination, i.e. change the last color to 4, this will give you 124 as the second color combination. Change again to 5 to get 125 for your 3rd color combination. Repeat until you have exhausted all the color for the last color.

Change the middle color to the next color, e.g from 2 to 3, and begin the last color from 4 to get 134, repeat to change the last color until 8 and so on….

If you only have 7 yarn colors, just delete the combination number that contains an “8”. Follow the chart to crochet your tricolor granny with only 7 yarn colors.

This chart is for 8 yarn colors and 2-color in each square.

This chart is for 8 yarn colors and 4-color in each square.

### Color Permutations

For each color combination, you can alter the sequence of color to make them different.

A 2-color square will have 2 color sequence. A 3-color square will have 6 different color sequence. A 4-color square will have 24 different color sequence.

An example of 3-color square with a different color sequence.

### Crochet Granny Square

After you have marked your yarn color with the number and understand how the chart works, you may begin to crochet the granny square.

Prepare some boxes or containers to keep the work-in-progress squares as you will need some time to finish the whole project.

This is how I did my granny square but you may follow your own preference in the crochet order. From the chart of 8 color tri-color square, we have 21 squares in the color 1 (rightmost column), so crochet 21 pieces of round 1 with color 1.

Crochet 6 pieces of round 2 with color 2 (set A), 5 pieces of round 2 with color 3 (set B), 4 pieces of round 2 with color 4 (set C), 3 pieces of round 2 with color 5 (set D), 2 pieces of round 2 with color 6 (set E), 1 piece of round 2 with color 7 (set F). Align them into a triangle as shown in the picture where set A is on the vertical right and set F is on the left.

Crochet round 3 in the following manner: color 3 on set A; color 4 on set A,B; color 5 on set A,B,C; color 6 on set A,B,C,D; color 7 on A,B,C,D,E; color 8 on A,B,C,D,E,F.

Stack up and keep them into a box and label color 1.

Repeat the method to crochet with color 2 as round 1, 15 pieces of them.

Crochet 5 pieces of round 2 with color 3 (set G), 4 pieces of round 2 with color 4 (set H), 3 pieces of round 2 with color 5 (set I), 2 pieces of round 2 with color 6 (set J), 1 piece of round 2 with color 7 (set K). Align them into a triangle as shown in the picture where set G is on the vertical right and set K is on the left.

Crochet round 3 in the following manner: color 4 on set G; color 5 on set G,H; color 6 on set G,H,I; color 7 on G,H,I,J; color 8 on G,H,I,J,K.

Stack up and keep them into a box and label color 2.

Repeat the method to crochet with color 3 as round 1, 10 pieces of them.

Crochet 4 pieces of round 2 with color 4 (set L), 3 pieces of round 2 with color 5 (set M), 2 pieces of round 2 with color 6 (set N), 1 piece of round 2 with color 7 (set O). Align them into a triangle as shown in the picture where set L is on the vertical right and set O is on the left.

Crochet round 3 in the following manner: color 5 on set L; color 6 on set L,M; color 7 on set L,M,N; color 8 on L,M,N,O.

Stack up and keep them into a box and label color 3.

Repeat the method to crochet with color 4 as round 1, 6 pieces of them.

Crochet 3 pieces of round 2 with color 5 (set P), 2 pieces of round 2 with color 6 (set Q), 1 piece of round 2 with color 7 (set R). Align them into a triangle as shown in the picture where set P is on the vertical right and set R is on the left.

Crochet round 3 in the following manner: color 6 on set P; color 7 on set P,Q; color 8 on set P,Q,R.

Stack up and keep them into a box and label color 4.

Repeat the method to crochet with color 5 as round 1, 3 pieces of them.

Crochet 2 pieces of round 2 with color 6 (set S), 1 piece of round 2 with color 7 (set T). Align them into a triangle as shown in the picture where set S is on the vertical right and set T is on the left.

Crochet round 3 in the following manner: color 7 on set S; color 8 on set S,T.

Stack up and keep them into a box and label color 5.

Crochet the last piece with color 6 as round 1.

Crochet round 2 with color 7.

Crochet round 3 with color 8.

You have complete all 56 tri-color combination.

Take out 1 granny and it’s 3 yarn colors to crochet another 5 pieces in different color sequence.

Stack them back to the container and bring out another piece of granny to repeat the color sequence until you have finished all of them.

Crochet the white border to complete the squares. The squares are now ready to join up to make a blanket.

How come you don’t use color 1 or 2 in a 3 color sequence as the final round? Or colors 1,2,3 in a 4 color combo? You can get quite a few more unique combinations if you backtrack the numbers in excel!!

Craft Passion -

Maria, can you further elaborate on which one are you referring to? I would think that your idea could be a repetitive combination since I have done it with a formula to find out the exact numbers of combination before putting them into pictures for easy understanding. I would be happy to know if there are any possible extra blocks of color to make. Thanks.

Anna Maria -

Good morning, I write from Italy

congratulations for the beautiful blanket, and very pretty in the explanations, unfortunately not well understood the scheme

for the combination of colors

thank you

Leona -

Hi, I have to say that I tried several times to make my unique color combination (5 colors in total, and 4 colors per granny square) but I absolutely cannot make the maths out of it, not even in Excel. Is there anywhere online a calculation tool or generator which would give me a visual aid to make the unique color combinations? I feel very unhappy that I cannot make the maths. Thank you so very much for all the great tutorials which have given me enormous joy while replicating and learning my first crochet stitches.

Judy -

Thank you so much for this great tutorial. It took me a few times reading through to understand the charts and how to use them. As soon as the rest of my yarn arrive I am off and running! Very cool post!

Wendy -

Thanks for sharing this! I ended up making my own Excel spreadsheet based on your sample for a different blanket. I’m now using it to mark off each color combo so that I have no two squares with the same colors. Just wanted to share that with people who are wanting all unique squares…I just print out the spreadsheet and cross off each color combo as I use it, this way I have random colors, but no repeats, and I’m joining as I go. Thanks so so much!!!

Craft Passion -

That is brilliant, Wendy!!! Glad that you are able to work it through to come up with your own no repeat of color combination for the grannies.

Cookcroc -

What a contribution to the crochet world! Your approach is excellent.

I do have a question for joining with the flat slip stitch. My squares are evenly stitched. The border was two rows of dc. Even after steam blocking I’m having trouble getting them to line up. I’m not having a problem with the slip stitch but connecting them vertically to create a strip my top and bottom edges drop out of line. My corners are 5dc and I’m choosing the stitch that falls over the middle dc.

Can you figure out what is going wrong? I’d appreciate your help. Thank you.

Craft Passion -

Hi Cookcroc,

Do you mind sending me a picture of your squares via contact form, it will make a clearer understanding of your problem ๐

Thanks.

Cookcroc -

Was not successful putting up a photo. Sorry.

Washed squares thinking that would help. Used slip stitch in back loops to put it together. The squares had a step like appearance but I bordered it anyway.

Washed the finished blanket and pinned it (profusely) to a bed and let it dry. There has been improvement but it still has a real sway to its appearance. We all like it but next time I think I’ll keep more open corners to use when putting it together.

Thanks for your time.

Varsha -

Hi ,

I loved the sunburst granny squares blanket.Can i use 2 ply wool to make it? Also would it be wise to put a liner at the back?

Craft Passion -

Hi Varsha,

2 ply wool will make very small granny square, so, either you are going to have a small blanket or you will need to do more squares to make up the size.

Yes, you may add backing to the blanket, fleece will be a good choice. Block your blanket and pre-wash the fleece before having them sewed up together.

Hope this helps.

Happy crochet.

Carmen -

Great blanket. Once you had all your blocks made, how did you determine the order to connect them?

Craft Passion -

Hi Carmen,

This tutorial will answer your question and future questions. It is the tutorial of how I made up a blanket by using all these blocks. ๐

Happy crochet day!!!

Linda -

Hi,

How would I use your chart and use approximately 25 different colors with 3 color combinations to a square. I appreciate any info, and am thankful for you sharing your pattern.

Craft Passion -

Hi Linda,

If you are taking about the total number of granny squares you will get out of 25 different color with 3 color combination, you will need to use the nCr calculator to find out the unique color combination. Enter 25 as the value of “n” and 3 as the value of “r”, you will get a result of 2300 unique color combination. Multiple 2300 by 6, you will get 13,800 total number of granny squares. Hope this helps.

Novi -

Hi Joanne

This is an amazing looking blanket. Thanks for being so generous in sharing your wonderful patterns. May I ask how many balls of each colour you used to make the blanket?

thanks

Novi

Craft Passion -

Hi Novi, thank you for loving this blanket. I used 1 ball for each color (8 colors), and 9 balls of white. The complete tutorial is at another tutorial post, please read it here for more info. Happy crochet.

Trish -

thank you so much . Great gift from you to all who crochet

You are most welcome, Trish ๐

Sheila -

Hi” I started crochet recently and came across your site while googling complimentary colours for a granny square ! Would have settled for a square , but then I saw the colours and with God’s help am at the end of the first part and my question is why did you have us stack finished work in separately? Seeing that you are methodical and mathematical I wonder is that the order to join them?

Looking forward to your reply and thanks. Sheila

Craft Passion -

Hi Sheila,

Good question. I crochet them based on the color combination, for example, pink (P) + yellow (Y) + blue (B), as explained in the tutorial that these 3 color can made up 6 sequence combinations. I just stack 6 of them up after I finish off with this combination.

I have no particular method to place them before joining up, I just pick up the squares randomly and lay them on the floor to form a big blanket. I did a few adjustment on the placement to make the color spread evenly.

Lily E -

Hi, it is easy for me to understand it and I want to do it sooon…but… I need to buy supply for each color (since I don’t have any…I am beginner :).

Please help me by giving any information e.g: what kind of yarn should I buy, how many skein for each color, etc.

Thanks in advanced.

Craft Passion -

You will find the information you need to start working on the blanket in the Sunburst Granny Square Blanket pattern page. Happy crochet ๐

Janice -

Can I know how much yarn u used?

Craft Passion -

I used about a total of 17 balls of yarns for a full size blanket of 66″ (W) x 86″ (L), you may find the complete pattern of the blanket here.

Lou Ann Elliott -

I’m sorry, but I’m not understanding how you get the 336 blocks using 8 colors, 3 rounds. I’ve made the first set of 56 blocks following the tutorial. I see in the pictures the squares in the triangle are stacked so I’m not sure what color combinations are underneath. I was never good at math. ๐ I love the pattern! Thanks.

Craft Passion -

You are on the right track. 56 blocks is correct, now what you need to do is alter the order of the color on the round of the granny, each one of 56 block will have 6 different color orders, 56 x 6 is 336.

Erica Lopez Orellana -

Gracias por esto es maravilloso empese a comprar hilos y aprender a tejer me encanta , ojala que me pudieran alludar mucho mรกs .

Translation (by Google):

Thanks for this wonderful empese to buy yarn and I love to learn to knit, I wish I could alludar more.

Manju Krishnamurthy -

Thanks a lot. Your work is excellent and easy to follow. Just wanted to know can I use crochet thread for this blanket. 3ply baby wool should also be good for the same. As I m staying in India, the climate is moderate.

Craft Passion -

They should work well with the similar weight yarn and 4mm hook size ๐

julie -

is there a pattern, as I know there are many different patterns and I love this. Thank You

Craft Passion -

Pattern to follow soon in the next tutorial. Thanks for liking it ๐

Pat -

I would like to make a patchwork quilt using the pocket method, any tips on how best to make the pockets?

Craft Passion -

Hi Pat, sorry, I wasn’t sure what’s you question is. Can you please elaborate it more?

Polliejean -

This is amazing! Thank you so much for sharing it with us! I’m starting a baby blanket now, my first obe, have made 30 squares so far and was already worried I had to repeat! I will use your chart! Thank you again! ๐
