I stuck the head of the screw into the cone (remember, it’s styrofoam, it’s gonna make a nice little tunnel), female loki costume and then pulled the screw out again. I added a dot of hot glue to the screw head and reinserted the screw. Protector for added protection ! We first did a bottom layer of silver paint for a shinier metal look. Once the smooth foam was dry (only a few minutes after application), it was time to paint the cones.
