This was a super fun project for my daughter to do. She was already excited to have a unicorn "hat" but what made it even cooler was that the horn lights up!! She loves it.

We had a hat contest for Easter last week and my niece wore her unicorn head and won $100 from our Aunt. First kid to win the hat decorating contest.

My daughter absolutely loves her unicorn costume. My daughter is 4 and wanted to put this together herself, but needed my assistance. However, I do believe this project was rated for older children. It looks great. The other kids and parents in the area want to know where we got it.
