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.

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.

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.

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.

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.

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

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.

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

Craft Passion -

Wow wow, can’t wait to see your blanket, please share with us about your progress ๐

Janice -

This is so beautifully explained and presented! Thank you!!

Tiffany -

This is wonderful! I am a math teacher in Texas. We are covering this very subject in my class right now. I’m going to show this to my students. Thank you!

Vivien -

That’s cool! May I know what yarn did u use for this?
