My chin absolutely loves his, it's a fleece star shape, I got it from Hammocky Hammocks (UK based, but they do ship). It lives in his hammock, and he alternately sits on top of it and 'guards' it, and curls up around it to sleep. If I ever dare to touch it, he glares at me.
If you want to sew your own, it might be an idea to try to keep as many of the stitches as possible on the inside - you do this by sewing the two pieces together inside out, then turning them right side out before you put the stuffing in, then close the gap with a few extra stitches (these do have to be on the outside). That way it's harder for a determined chinnie to pull the stitching out.
