I used hard wire to hold the shape and simply sewed the shapes onto the wire.
This was my first attempt:
Its one you wear around the back of your head.
Later I searched the net and realised most popular ones are the head band style ear muffs.
So, I made those too!
Took me a while to make them and my dad had to help bend the wires.
The furry ones are available on my etsy shop!
