I have had Quilt Pro for a couple of years and I use it a lot. You can design any size quilt, the program automatically sizes the blocks to fit your design. You can scan in your own fabric. It will print out how much of each fabric you need. I usually just do print preview and it shows what would be printed and I write those measurements down and head off to the store. I don't understand how this "block a day" works, if it costs extra from the program and if you can get the blocks without having the Quilt-pro program.
