I hot glued the lights into two rows around the mane making sure that the hair wraps around the lights to keep them in place and also to make the hair stand up a little more. I positioned the lights in a zigzag formation to give the appearance that the copper was part of the hair.
I then used a red paint marker to make some of the mane a deeper red color in some areas.
I used some hair gel to make the hair stand up in a wild fashion like the movie. You could also use tacky glue for this, just make sure it's completely dry before placing on your dog.
