I don't cut out everything beforehand. First I cut just enough to make several blocks to make sure they come out the way I expected, fabrics go well together and they are the correct size. You never know if you cut the pieces wrong and waste fabric or, what I usually do, change my mind about the block. After all my blocks are made and trimmed I'll cut the sashings and then the borders. I leave the binding for last. If I don't have enough fabric for the binding I can always piece several of the fabrics from the quilt to make the binding, I'd cut each fabric strip 18 to 20 inches.
