Anyone know of cheaper alternative material to plexiglass for homemade DDR pad arrows?
What the title says. I want to build a new wooden DDR pad, but this time spending as little money as possible. Plexiglass sheets make a great material for the arrows (see this video: http://www.instructables.com/id/DDR-dance-pad/ ) but it drives up the cost of each pad by about $25. So I'm looking for a cheaper material that I can cut into squares for the arrows/buttons; it needs to be at least slightly flexible (so it can warp downwards slightly when stepped on) and obviously sturdy enough to withstand stepping, but it doesn't need to be transparent or plastic. Any ideas?
