I want to make this pattern,but I want to start with a 9 1/2 block instead of 8.5. How wide would I then cut the strips??? Would I just divide by 4??

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

The important question is whether the 9 1/2 inch is the size square to start, or if the goal is a 9 1/2" pieced block to put into the quilt, or a 9 1/2" finished size of the block after it is sewn to the blocks around it in the quilt!

You're not subtracting the seam allowances. Every time you sew two strips together, 1/2 inch gets subtracted from the total of the 11". Sewing four strips together will subtract 1/2" three times or 1 1/2 inches. 11 minus 1 1/2 equals 9 1/2. Then when the blocks are joined to each other, an additional seam allowance is taken off both sides, equally a 9 inch finished block.
