Outline work is a form of embroidery, in which only the outline of the design or pattern is stitched. The rest of the design is left ‘bare’, showing the ground material, or sometimes an applied piece of cloth. The stitches that are often used to work this style of embroidery include back stitch, chain stitch, outline stitch and stem stitch.
