Duplicate stitch is a method of adding colorwork to knitting by sewing afterwards. This is great for very small amounts of colorwork.
How to Duplicate Stitch:
Thread tapestry needle with yarn tail. Anchor yarn on WS if needed.. *Bring needle to RS at base of stitch (at bottom of “V”), then at the top of the stitch, go underneath the 2 legs of the stitch above, bringing yarn and needle through on RS. Put the needle back into base of stitch where it first came out, going to the WS. Rep from *.
