Jenny Doan, Missouri Star Quilt Company, demonstrates joining the final strips on The Ultimate Quilt Binding Tutorial -- toward the end of that tutorial, she tells (and demonstrates) how to join the final seams of your binding so that it will always fit. I still make mistakes -- I always will because I'm human -- just like all the rest of you. I sometimes get furious at myself when I make a mistake, but getting furious doesn't accomplish anything. We have to just laugh, back up a step and fix the problem!
