Okay... If you start out with a 9" square and divide it by 4, each strip would be 2 1/4" wide.
If you start with 9 1/2" and divide it by 4, each strip would be 2 3/8" wide :D:D:D
BUT***
These blocks are cut diagonally, and stitched.... so now the dimension of the block has changed :wink:
Edited*** So you square it up to 9" and then divide it by 4 :D:D:D
