Jacquard tells us:
“iDye Poly is virtually the only dye that will colour polyester. In fact, it will colour almost anything synthetic, including plastics and nylons, buttons, frisbee discs, Worbla & Thibra, 3D printed objects, toys, dolls, wigs, cleats, urethane coatings and more. The dye comes in a dissolvable packet, so there are never any messy powders to handle: simply drop the packet in a pot of water, add the fabric or objects and bring to a simmer.
An essential tool for cosplay artists!”
