I had a problem with the tool also. I was not using the tool correctly. I, too, watched the video. Now that I am using the tool correctly, I love it! Until I got the tool, I had so much trouble joining the binding. I can remember ripping out the binding joint four times before I got it right on one quilt. I never bound a quilt without having to rip at least once. Now, I have a perfect join every time thanks to the Missouri Star Quilt video.
