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.
