In VStitcher, each colorway is a combination of color, seams, trims, fabrics, and artwork. You can have multiple colorways for a garment, allowing you to readily view different appearances for the same underlying design.
VStitcher automatically creates a colorway for each garment, and updates it as you make changes to the color, seams, trims, fabrics, and artwork.
For more information, refer to Colorways in VStitcher.
