I bought green, white, and black felt. They were $0.20 each. I already had a blue felt sheet at home so I didn't need to worry about that. And then I bought a $7 fanny pack.
I put the green felt in my embroidery. Then cut out a white circle and sewed that on.
Finally I attached it to the fanny pack. The pack is empty right now but will definitely round out when I put my camera and such in it. I'm excited about this one!
