Follow the instructions carefully. Standard sewing techniques will handle repairs to the fabric components. Lycra components that stretch during use such as jumpsuits must be overlocked. Areas that cannot be reached by machine must be handstitched. Do not remove the skin from the headpiece as damage will result.
Replacement sweatbands and tongues are available as spare parts.
Webbing may need to be hand stitched as the normal domestic sewing machine may not be able to handle it. Polyethylene plastic components cannot be glued and must be replaced. Tubular rivets and the tools to set them are available from leathercraft suppliers. A heavy pair of pliers will set them in hard to reach areas such as in headpiece harnesses. Costumes designed for use in cold climates have poly carbonate eye moldings.
