Have it and love it. Don't know all about it yet but am slowly learning. Have printed foundation piecing blocks and a crab block for a friend. She couldn't believe I printed it for her. I found I really like foundation or paper piecing and it can allow me to print all the pattern blocks I need for a quilt. Can also tell you how much fabric to buy when you enter the size, pick fabrics, backing, etc. I think it is fabulous for a new quilter like me...
