If you need shelf space for your canned goods check out this tutorial for building canning shelves. I like these because they way they are put together you can disassemble them really easily. These could be called nomad canning shelves because for folks that move around a lot these could be put up and taken down as needed.
Instead of the shelf supports being nailed or screwed to the corner posts, the posts have cut outs for the supports to slide into and make this nice and sturdy but leaves it all ready to be disassembled quickly and easily.
