A good way to figure out a dragon is to adapt a dinosaur pattern... or a horse pattern... unfortunately, there are no simple felt dragon patterns out there.
There is a seller on eBay who always ends up for selling around $10 and her pattern is based on her horse pattern, looks like it.. shorter leggs, longer body and big wings and tail...

I have a pattern that I made cut out but I have never had a chance to sew it up... hopefully someday....
