The Binding Tool from TQM is a must-have for every quilter. It's designed to eliminate the bumps and lumps that are so common when joining the ends of your binding.
Use this acrylic tool to make two measurements and two cuts and you're on your way to a perfect, smooth finish.
Instructions are printed on the tool. Plus one quilt shop has put together a wonderful video that steps through the process which you can see below.
Available in two sizes.
