It cuts your squares, triangles ect...problem is that if your pattern callls for a 2 7/8 in square, you can't use it...It is only good if the templates and the pattern jive....There are limited templates available....and they are pricey...It's a good thing if you can design your own pattern using the themplates that you can buy or if you are making several quilts that require the same size squares, triangles etc...Lots of money not alot of return...
