I saw a headband like this for sale on Etsy, and this was my attempt at it. I love the way it turned out, so sophisticated. It's lovely alone, and it would be a great base for a flower or other decoration. Tie-backs make great gifts, since they fit such a range of head-sizes.

Baby size should fit through toddler; kids, teens and adults should all be able to use the adult size. If you find your chains very tight or someone has a bigger head or very thick hair, simply add chains to the beginning chain and the end chain.

Finish off, trim ends short. If you are worried about the yarn loosening, you can add a dab of glue to the knots. Weaving in probably won't work because a headband gets stretched a lot, and the weaving in would loosen and become visible.
