So I can pretend to be a deer much more effectively.
Cut two lengths of wire to the desired length of your antlers plus a few inches for attaching them to your head band. I used coat hanger wire because I had nothing else around, you can do this but it's a little tricky to bend.
Wind tape around and around the whole wire construction until it is sturdy and the desired thickness.
Optional steps: paint the antlers or add fake flowers, strings of beads etc.
