These are the pieces you'll need. Two ears, a horn and a headband with two prongs. Yves used wire we bought at Michael's to attach her horn to her forehead.
For the ears:
I used a piece of glitter foam, because it's sturdy enough to stand up on its own. I thought about using pipe cleaners and felt, but this was more convenient.
I freehanded ear shapes and cut out four ear pieces.
I glued the pieces back to back and wedged them into my headband.
For the horn:
I drew a triangle on a piece of cardstock. 6 inches tall and 4.5 inches at the base.
I rolled the triangle into a cone and stuffed it with newspaper to reinforce it.
Then I cut a strip of gold fabric to wrap around the the cone. The fabric is a little messy, because it used to be the belt to my Wonder Woman costume.
I used a combo of these two adhesives to get the fabric to stick.
This is the completed cone.
Remember to leave a strip of fabric at the end to attach it to your headband. I wrapped the fabric around the headband and tucked it back into the bottom of the cone and stapled the fabric to get it to stay.
For the hooves:
I just folded a piece of fabric into a small rectangle, about 5 inches long and secured it with liquid stitch. Then I wore it kind of like an arm warmer.
