This great little technique can be used to add sections of color designs to stockinette. (It reminds me of cross stitching.) Many knitters use the Duplicate Stitch in lieu of small areas of Intarsia. These added stitches are placed on top of stockinette stitches after the piece is complete with the use of a tapestry needle. The Duplicate Stitch is also a great way to cover errors and wonky stitches you wish you had discovered prior to binding off. I especially love to use the Duplicate Stitch when weaving in ends on the right side of the work is needed.
