Cut an oval that is about 3 inches long for the mouth out of foam paper
Cut white teeth to go on the front and back of the mouth
Glue both on the underside of the sock so you have a mouth with teeth at the front and the back
Cut stiff felt, felt or foam paper to make the spikes going down the dragons back and glue it to the top of the sock going down the middle
For the eyes, glue the googly eyes to the front of the large pom-poms and glue those to the top of the sock where the toes would go
Add the two smaller pom-poms in front of the eyes as nostrils
Glue the tear-drop pieces of felt to the back of the eyes so the pointed ends peak over the eyes
Make fire for the mouth out of your felt and foam. I made it look like a forked tongue, but you can add more cuts to make for flames. Use red as the base and make a smaller yellow to layer on top
