I generally remember that I should have cut my border first after the center is done and I realize I'll have to piece the border. lol
If I have a limited amount of fabric and I can't get any more, I spend a lot of time doing the math to make sure there will be enough. The old saying: measure twice cut once comes to mind...... Inadvertantly, I'll miscut, mismeasure, or missew, and that's where creativity and a visit to the fabric store come in. :lol:
