Have any of you quilters out there used the Fons & Porter Binding Tool to bind your quilts? If so, how do you like it? I have one and cannot understand the directions - I must be really stupid here. It says to cut the right binding off in the center of the opening. The first time I did this, I cut it off too short, so had to add another piece of binding on so it would be long enough. I'd like to hear from you quilters out there if you've used this tool. Thanks Much!
