I have been admiring some older quilts, probably made around 1950 and see that the binding is about 2 inches wide - looks like the bindings I see on blankets. I usually make my bindings - cut bias fabric 21/2 inches, fold in half, stitch on and fold over the quilt edge and stitch down again; ending up with about a 5/8 inch finished binding. Does anyone know what is the perferred width?
