This is a very cool tool. You can make and view one block and it multiplies it so you can see what a whole quilt will look like and I am lucky to own one. I talked about this a while back on along ago thread, and when I did a search for someone to find it, The info said no longer available at several locations. so if you can get your hands on one, do it, if you really want it. Mine came from a local quilt store many years ago.
Maybe it is available again. That would be great.
