thanks for the information but now that you brought this subject up. Why when we are measuring for a 12 1/2 block that before it is done it is less. Am I not cutting right? At times say a 6 1/2 by 6 1/2 turns into a 6 1/2 by 6 and almost a 6 1/2 but like to marks short.
This I really need help with.
