Made the mustache myself.
Materials used: thick cardboard, black felt, black spray paint, spray adhesive, nylon straps, hot glue, & staples
Cut two identical giant mustaches out of cardboard. Spray paint one side of each. On the other sides, use spray adhesive to attach the felt. Cut off excess felt. Attach nylon straps. Staple and hot glue from the inside to secure everything. Enjoy!
