are they just plexie-glass on top of a box of wood? how do you get the plexie glass to stay on the wood? (glue?) I know there is that plastic stupp you can heat up and it will bend. is that what you would us for a rainbow?
All I can do is 50-50 a box right now. is sliding one easyer or harder than a flat rail?
