My wife and I wanted a nice way to hide more of our son's toys in the living room that didn't look tacky. We actually bought the cubby bins before even deciding what to make. (From target of course.) I made the bookcase out of wood shelving that already looked kind of beat up when I bought it knowing that the wood stain wood bring some character to it.
I only changed the plans slightly by making the legs flush with the inside so I could trim the ends and customizing the size of the cubby openings to fit the bins. (Mine aren't actually cubes.)
