After step 2, on Bonnie’s blog she said that her strings didn’t even make a dent. And I have been doing the stash challenge and trying to figure out how much yardage “didn’t even make a dent” is. So here is my math:
- Average strip size was about 1.25 inches (if yours were bigger or smaller, you need to adjust this). Finishes at .75 inches.
- So that means that 40% of my fabric is in seam allowance. (.5 inches seam allowance/1.25 inch strip= .40 or 40%)
- Adjustment to the 40%. Well, I was trimming a lot of triangles off the ends when I gave each string unit a haircut. So let’s say that’s another 10% fudge factor. [See my picture. There is a tiny bit of purple and white in there, but most of this is from the strings.]
- Finished unit is 3.5 inches square, or 3.5 x 3.5 = 12.25 square inches
- Unit adjusted for seam allowances is 12.25 x 1.50= 18.375 square inches of fabric (including the seam allowances and cut off corners) per string block
- 72 units x 18.375=1323 square inches total fabric used in the string blocks.
- One yard of fabric at 42 inches wide is 36 x 42= 1512 square inches.
1323 square inches / 1512 square inches = .875 yard or 7/8 of a yard!
Wow, who’d have though we used nearly a yard for all those strings?
