This is a pic of 2 dragons I tatted. The patterns are by Anne Bruvold and here are the links:

http://www.nuperelle.net/drager/monstre/MinidragerEng.pdf This is for the larger dragon
Anne has done a fantastic job of designing these patterns.
I have a book with some dragon patterns for sale at my stores by Karey Solomon. I haven't tried any of them but if you're a dragon lover like me you may want to get a copy.
