Anyone have a sheet goods storage rack that allows storing 4x8 sheets vertically on the 4' end? With my 12' ceilings I'm thinking that could be a nice way to go for longer term storage. I built a roll-around cart, but it is very hard to get to the back sheet (which is always the one I need,) its full because of a bunch of material I got at an auction, and its hard to move. I'm thinking I might just use it for current project materials and build the upright storage for everything else. If you have pictures, I'd love to see them.
