I happen to love to make 1/2 square triangle-type quilts and I have that tool and it is, above all the rest of my "tools" the best and most precious to me! It makes making 1/2 square triangles so easy and so much fun. Mine is a Fons and Porter and I had two in the package. I like the shorter one the best and so I gave the longer one to a friend who has just started quilting and she is used to the longer one and likes that one!
Isn't it neat how everyone has one special tool? I love how everyone does something different and it still turns out beautifully. I always go by "My Quilt - My Rules" and that seems to work for me. Edie
