Introduction: Crochet Boot Warmers
Chained 20(or as wide as you want), add one chain turn and single crochet, chain two turn double crochet..repeat until you have the length you want(usually fits around your leg) sew together to make a tube. along the one edge where the single stitch goes you slip stitch and where the double crochet double crochet 6-7 stitches in the single loop area until finished. then finish off by slip stitching into ends together.
I will apologize if this doesnt make sense but i am not good with instructions hope this helps-ish..
