Okay... I had to go look and see if I could find a video showing this foot. I think I'm going to demo it at my next quilt guild meeting. Wow. It's a cool foot for a lot of things. We have a few ladies that are working on applique quilts and this foot would make life a lot easier for them as well.
I thought I'd share the really good video I found
