I ended up with one leg warmer, so I divided it into a pair of ankle warmers! I forgot to take a before pic, however the idea is pretty simple.
You’ll note there are 14 little puffballs on this piece, 7 on each side.
I cut it on an angle, allowing 7 on each half.
Then I hemmed it with a zig zag. This could also have been done with a serger or a blind hem, but as it is knit, this easy job blends well.
