To make, you need a couple of packages of white coffee filters (or brown, or you can dye them. Wouldn't a red and green one look cute?). Pinch each filter in the middle and then do sort of tri-fold so that it makes a fan shape. Then just string them one by one onto a piece of thread! So simple and the filters are pretty sturdy. My cat hasn't been able to pull the whole thing apart yet, even though she has tried repeatedly.
