And Primitive Gatherings makes 2 more smaller Twister Tools.
They use 3.5 in sq. and 2.5 in sq. They are fun too !
We give classes on the Twister at our quilt shop and I would say, that is the most fun way to learn to use it. Sometimes the directions can be a bit confusing....so take the class and have fun with others !
I am working on twisters all the time LOVE THEM !
