I saw a binding tool in a Clotilde catalog today. It is a wooden tube that flares out on each end to keep the binding wound in the middle. A string or ribbon goes through it and the quilter wears it around her neck while attaching the binding to the quilt. This keeps it from dragging on the floor and picking up dust, dirt and dog hair. The tube just spins as the binding rolls off of it. I have a vague memory of someone substituting an empty toilet paper roll and using it on a string around the neck in the same fashion. That is certainly cheaper. I never remember to try it.
