Remember that the setting triangles on the side of your quilt is actually a square cut on both diagonals, while the triangles in the corners are actually a square cut on one diagonal.
In this manner, you keep the bias edges sewn to the inside straight blocks, while the outside of the triangle is actually on the straight of grain.
If you measure one side of your block and add 1.5", you should have enough to cut on both diagonals for your setting (side) triangles.
If you measure one side of your block and add 7/8" or an even inch, cut on one diagonal -- you should end up with a corner triangle that is more than ample for your quilt. <wave>
