you will love this. The first day I bought mine I took all of my scrap fabric and turned it into different squares and put them into clear bins. I have used those squares in applique alot and of course if I need a square I have it as well. I can't remember what all of the sizes are but if you go to accuquilt.com you'll see all of the different dies they have and patterns you can get; some are free. The main thing is to watch the grain of fabric so it doesn't stretch when cutting. The instructions tell you this. You can use a marker and mark on the foam around the blades to that it is easier to see the cutting edges and where to place the fabric to make the smallest amount of waste.
