Small for a dragon, but pretty big for an amigurumi - they are about 17.5" long and have a wingspan of 22". Of course, if you're a Lego person, they are just the right size for a ride, as one of my pattern testers discovered:
I'm very happy, after a certain amount of experimentation, with the wings. I managed to make them fairly stiff without using any wire or anything else apart from crochet and stuffing. I also tried out different eyes - they can be made with either safety eyes (ones with a slit rather than a round pupil look best, I think) or with round beads - the red Dragonet has clear glass ones.
If you want to make your own Dragonet, the pattern is for sale in my Etsy shop:
