Step 7: Accents and Details
I decided to change the types of horns that the dragon had, and to give myself a little more height clearance.
To do this, I again used 2 pieces of PVC Plumbing pipe that I had,
1. Cut the PVC piping to the approximate length of the horns you are adding.
2. Drill into the skull of the costume approximately 3-4 inches ensuring that the bit is about the same size as the piping. Using a slightly smaller bit OK, because the foam will hold it tight
3. Use a hot air gun or blow torch to bend the PVC Pipes to the curves you want.
4. Cover 1/2 of the individual horns with the expanding foam to give it a look you wish. You could also use the Paper ache, or the Light Weight air dry modeling clay to give it a more sharp look. Be sure to allow the 3-4 inches on one end to be clear so that you will be able to more easily insert the piping into the head. : Note, I covered mine AFTER i'd hot glued them into the head, to allow for a more clean join where the head met the horns.
5. Let the Foam/glue/Clay dry, and then do the other side
6. liberally cover the ends of the PVC pipes in hot glue up to 3-4 inches and insert into the holes you've bored into the skull.
The spikes were literally pieces of left over foam that were cut off from the inside of the dragon from previous steps
1. Cut a flat strip along the back of the dragon's head/neck
2. Cut Your larger foam cast offs into spike Shapes
3. Hot glue the spikes to the flat space left along the neck/back
4. Spray paint the appropriate color
