LF: black egg crate

[msjboy]

shops in usa will send it up here ( eg eplastics.com) and the stuff is the better more rigid type being 3/8" thick than the flimpsy stuff everyone buys at your ronas/lowes/home depots... about $14 I believe for the white 3/8".

You can also try industrial plastics, or any commercial ceiling or commercial fluorescent lighting company - ask around your lighting stores and they might give you a reference. Up here in Vancouver, looking for the stuff myself, one sheet of black is between $27 and $35.00 ( compared to a 3/8" white sheet being around $14.)
