Our website provided a free download of QuiltPro 5.2 for Mac. The application lies within Lifestyle Tools, more precisely General. This Mac app was originally designed by Quilt-Pro Systems.
From the developer:
QuiltPro can create a quilt and see it come to life without ever cutting a scrap of material. Experiment with designs, play with fabrics, move blocks, overlay stitching, all with only a few clicks of the mouse. You can design your own blocks or work with the block library, scan in your own fabrics, and create custom quilt layouts and pieced borders.
