I've had Quilt pro for years (am I really that old?) I use it all the time, at first I just laid out quilts constantly, but now I use it to judge yardage for patterns and to do a trial layout. I use the quick layout for deciding on size of quilt blocks needed to make the size quilt I want to end with. I upgraded to 5 but they may have a new version by now. Well worth the money.
