There is a simple formula for figuring out how wide to make the strips on your blocks, as well as the half-square triangles for the corners....especially if you want regular sized blocks to put into a 6 1/2" or 12 1/2" format. In a nutshell, subtract 1/2" from the fussy cut piece. Then subtract that measurement from 6, 9, 12 or 18, whichever gives you a number between 4 and 8. Divide that number by 4, and add 1/2. This will be the size of the strips for the sides of the Hole in the Barn Door block. Go back and take the number again before you added the 1/2. Double it and add 7/8. This is the size of the squares you will need for the half-square triangle corners. Let me know if you would like more specific instructions: I'd be happy to post them.
