The teal cat-ears are one of my favourites. They are hand made and each headband takes about one hour to make. I cut the pieces from my own pattern, and then hand sew them together to make ears. I then sew the ears to the headband and finally finish with the satin ribbon bows. I try to make the bows almost the same on each side, but of cause it is very difficult by hand to have them identical, so each bow and each head band is a little unique.
These headbands are available on my Etsy store (link here).
