Felt fabric is great for all kind craft projects. It's made with recycled pet bottles, comes with bright colors and most important thing is not frays. It makes to sew this fabric or just use hot glue like a dream. If you check the doll eyes I made a few years ago you'll how basic felt circles add some characters to and dolls and toys. 

For these felt doll eyes I used 2" wide white, 1" blue and 3/4" black felt circles. I just used some leftover blue and black DMC perle thread.
