Jewellery and Decorative Pieces
Cosplay jewellery is most convincingly made from jewellery-making components rather than from costume jewellery altered to match. Jewellery findings (clasps, rings, wire, beads) from craft stores provide the raw materials for necklaces, earrings, and decorative pieces that look considerably more refined than painted plastic. Resin casting allows creation of unique pieces — pour resin into moulds, add colour, cure, and finish.
Props and Weapons
Foam is the primary prop material for cosplay weapons — safe for convention carry, lightweight, and convincing when finished well. Closed-cell foam pool noodles form cores for staff weapons and swords; EVA foam provides the body and detail. All prop weapons should comply with the specific convention's prop weapon policy — check before building, as rules vary significantly.
Headpieces and Crowns
Wire-based headpieces use a base of jewellery wire shaped to fit the head, with decorative elements added by wrapping, coiling, or affixing with jewellery adhesive. Thermoplastic (Worbla) crowns are shaped when warm and hold their form when cool — finish with paint and metallics for convincing metal effects. Both approaches produce results that far exceed costume store alternatives.
