Nathan sure was busy this Halloween! He used InstaMorph all over customs for himself and his kids it looks like. He made a Robin (“Batman”) mask and some “My Little Pony” wings and ears for his kids. Later it was a Deathstroke (“Iron Man”) and Wonder Woman armor. He then painted them all with acrylic paints.
He started with sheets of InstaMorph (which you can make using a rolling pin, pasta roller, or two flat, hard surfaces pressed together) and then formed and cut them into the various shapes he needed. You can see the results in various stages of completion in the below pictures.
