Recently I was whining about my wonky flying geese, when someone mentioned getting Deb Tucker's Wing Clipper tool. Well, that bit of info made me realize that I had bought one a few years ago at a quilt show, put it up, and forgot about it......too late for the quilt I was making. Today, I got it out and began to use it for my current quilt I'm working on and IT IS GREAT!!! It gives you the different sizes you might want and the measurements to "over-cut" them so that when it's trimmed, it comes out EXACT!!! There is a web-site .....
www.studio180design.net I noticed there is a Wing Clipper I and Wing Clipper II now. I have the first one, and it meets all my needs. You might want to "hint" around for this for Christmas. Not affiliated, just a happy customer. Just my two cents.
