Just recently made a ton of flying geese for a baby quilt. I had not made any in quite a while. I tried the Eleanor Burns ruler that I own (but never used). MY geese turned out short a bit on the bottomside each time and I seemed to waste fabric.
Then I tried the Deb Tucker WING CLIPPER (which I bought after seeing her illustrate it.)! I am in love with that ruler...My geese turned out so perfect and I only trimmed off a TEENY TINY smidgen of fabric...I did watch her tutorial to help me out since I am a visual learner.... The WING CLIPPER is the way to go....the geese are so PERFECT... I HIGHLY recommend this method!!!
