This is not going to make any sense if you haven't read the Houndstooth Tutorial. This is simply where I've done the math for different sizes of strip and finished block using the equation specified. Here is what I said in the tutorial (everything in small font) :
*Now would be a good place to interject how to figure what size to cut your strips, and how to figure what size your final squares will be. If you like geometry, you would know the "a squared + b squared = c squared" would be the equation we need, though in this case, a and b are the same number. I will break this down for those that don't thrive on the math. Pull out your calculators and plug in these numbers. Let's say you want to have 1" finished stripes (be sure to add your seam allowances after doing the math). Here's how the figuring works:
1" (size of the finished strip) x 4 (number of strips per square) = 4
(answer from the last problem) 4 xª (squared - or if easier do 4 x 4 = 16)
16 ÷ 2 = 8
8 √ = 2.82 (square root)
This will be the size of the finished square using 1" strips.
Finished Strip Size - Finished Square Size
1" - 2.82"
1.25 - 3.5
1.5 - 4.24
1.75 - 4.95
2 - 5.65
2.25 - 6.36
2.5 - 7.07
2.75 - 7.77
3 - 8.48
3 .25 - 9.19
3.5 - 9.89
3.75 - 10.6
4 - 11.31
REMEMBER: ALL FIGURED ARE FINISHED SIZES - ADD SEAM ALLOWANCE
It can also go the other way. You know you want a 3" square finished. What size strips to you cut?
3 xª (or times by itself 3x3) = 9
9 x 2 = 18
18√ = 4.24
4.24 ÷ 4 = 1.06 (size strip to use)
Finished Square Size - Finished Strip Size
3 - 1.06
3.5 - 1.24
4 - 1.41
4.5 - 1.59
5 - 1.77
5.5 - 1.95
6 - 2.12
6.5 - 2.29
7 - 2.47
7.5 - 2.65
8 - 2.83
8.5 - 3.01
9 - 3.18
9.5 - 3.36
10 - 3.53
10.5 - 3.71
11 - 3.88
11.5 - 4.06
Hope this helps. Good luck. I'd love to see your finished quilt.
