Worbla & Thermoplastics

What you need

The build order

1. 1 — Pattern in paper, then foam

   Same body-traced patterning as foam armor. Cut the foam core slightly smaller than the Worbla so the sheets can seal to each other around the edge.

2. 2 — Sandwich the core

   Heat both Worbla sheets, lay the foam core on one, press the second over it, and squeeze the overlap. It self-bonds — no adhesive needed — and the sealed lip becomes the edge.

3. 3 — Heat form to the body

   Reheat and press the piece against a mannequin, bowl or your own limb through a barrier. Work in small areas; Worbla remembers every crease you put in it.

4. 4 — Build detail with scraps

   Nothing is waste. Roll offcuts into rivets, trim and rope; heat and press them on and they fuse permanently to the surface.

5. 5 — Smooth the texture

   Two to three coats of wood glue or gesso, sanded between coats, then filler primer. This is what separates convincing armor from visibly-pebbled armor.

6. 6 — Paint and seal

   Prime, base coat, dry-brush metallics, wash the recesses, then a satin or matte clear. Worbla holds paint far better than unsealed foam does.
