Start by threading your needle with the yarn tail you want to sew in.

Take your needle and yarn and follow the path of the knitted stitch, going under 2 strands of yarn, then following the path around, going under the horizontal bar, then back down under the next horizontal bar.

Then continuing to follow the path of the knitted stitch, bring your needle and yarn back down and under the lower horizontal bar.

Weave in your yarn tail for at least 3 stitches to make sure that it won’t come undone. Then trim your yarn tail, leaving a small length so it doesn’t work its way through to the otherside of your knit.
