My wife found this canned food storage system online and I just had to build it.
It was pretty simple to build. I bought a 4'x8' sheet of 11/32" plywood and had Home Depot cut it into 4 - 2'x4' pieces. At home I cut a couple 1"x4"s into 9 22" pieces for the dividers. I cut a couple 1"x2"s into 9 20" pieces for the front to hold the cans in. At the bottom I cut an angle from a 2"x4" and screwed an L-bracket to it to keep the cans from falling out. There was a little gap on the end not quite big enough for a soup or veggie can so I put a couple little shelves to stack small cans on or something. I didn't have time to build the second one today, but maybe tomorrow. I'm planning on building it with the divided sections a little smaller to hold smaller cans.
