If you’ve got an area you’d like to fill with shelving, this looks like a great solution — if you don’t mind the industrial look. And the brilliant part is that it takes almost no craftsmanship skill to make — just measure, decide on shelf sizes, then take a trip to the local hardware store.
Useful if you have a lot of heavy books, like me. The $30 Craigslist bookshelf I’ve got now seems to be working fine, but I can see those shelves sagging under the weight of my leather-bounds (books used to be a lot heavier, apparently). Probably a good intro to basic home crafts for the kids, too.
