I had an old tank top lying around and it wasn't very much fabric to work with. So I decided to make an anime-esc kitty hat from my friend and this is how it turned out. I apologize for the fact I look half dead in the picture, it was late at night.
The holes do stretch a bit because it was only t-shirt fabric. My advice is don't cut the holes to close to the edge. Give it a bit of room to stretch. Also, the lacing should be somewhat loose, it's more for look than function. If you decide to make it post pictures!!! If you have a question or need help ask!
