But there are some questions that arise when you are doing more than the standard charm pack. So we went to our users and they came up with some great info to work with. Try the following –
Here is what have discovered…Cut your squares of fabric:
3 3/8” = 4” Block
4 1/2” = 5” block
5 1/8” = 6” block
5 7/8” = 7” block
6 5/8” = 8” block
7 2/8” = 9” block
8” = 10” block
8 5/8” = 11” block
9 3/8” = 12” block
Now here is the formula, it blew my mind but thank goodness for calculators!
Finished block size x 1.41 = finished diagonal
Divide the answer, the finished diagonal, by 2. Add 0.875″ and round up to the nearest 1/8″ to find your parent block size.
There, aren’t you glad I just gave you the measurements?

Pretty cool eh’!! Just to be sure, I did make the 4”, 5”, 6” and 7” blocks with those measurements and they were spot on. I hope this helps you all! Let me know how it works for you.
