Thread your 15cm(6″)tail through a tapestry needle and tie off the end by pulling it through the next stitches and closing up the small hole that’s left after your bind- off. Tie a double knot to make sure it stays secure.
Step 21: Weave in the end by threading your tapestry needle into 5-7 stitches down into the fabric of your cuff and pulling your yarn end through them. Cut off the remaining yarn end.
Step 22: Repeat this process for the yarn tail left when you cast on at the other end of your welly warmer.
Step 23: Flip down the welly warmer’s cuff over the ribbed leg section and attach a cute button.
