This is so very easy to make. You just need to be able to cast on provisionally and to graft stitches. And knit of course.

If you want to dress it up a bit, it might be with a button/bow/flower applied to one side of it.

This was a very inexpensive project. I made the 2 headbands out of one skein.

This is knit with smaller needles than one would usually use for this yarn, but it’s because I like a firmer fabric for this headband.
