Okay, I know this is a wood working site but I was just wondering, have any of you guys used cardboard in any of your projects? Not for patterns, or sreading glue, but as an integral part the project - maybe even a structural component? I know Ian Kirby did a bit on torsion boxes and one of the side bars was for using Trico (basically a cardboard honeycomb) instead of the usual methods, and I've seen a few people use it like this: http://www.instructables.com/id/Cardboard-Lumber/ and somewhere on the Instructables web site, I thought someone had made a night stand (although I can't find it right now), and of course there's the myriad of cardboard chairs - but I was wondering if anybody's used on serious projects?
Just curious,
Todd
