: Art and Stitch and Pre-Design Studio are both invented by us, but developed by two different teams of software engineers. Where Pre-Design Studio II is an easy to use vector drawing program which can export to many longarm quilt formats, which can print pantos and has some wonderful stitch functions (Applique, jumpfree redwork, quilt patterns for embroidery machines), it is not a full digitizing program. Art and Stitch is an easy to use vector drawing program AND a full digitizing program, with an extensive library of ready made designs, motifs , creative fillers. So, two different programs, not an “upgrade”. See the comparison sheet between the two programs on the Overview page. Right now there is a nice introduction offer for Art and Stitch.
