File cabinet from thrift store, ceiling tile from Lowes, fitted, trimmed, and attached with strong double-sided tape (the kind used for the ceiling tile). Able to re-poke holes through tile for hardware. Voi la! Cute storage!
paint thinner on a file cabinet - taking it down to its natural metal jmoinajo edit: I did this before and really liked the look. wait to seal it, and you will get strange rust patterns from humidity. Seal with a clear gloss as soon as you like what you see.
