i never understood why, if you're adding 1/4's all over the place, you add 7/8 here. can anyone explain that in english? isn't it easier to make it a full 1" and then trim? not to mention that it's easier to see.
also, you talk about a 4" square made by adding that dratted 7/8. is this the same method used for making, say a seven and 1/2 " finished square? do you always add 7/8? i just go up to the next inch and shave off the extra.
