I found a medicine cabinet in the trash of a building that's being renovated. It was brand new--brand new!!--but someone had dropped it. The shattered mirror was still inside it.
One of my neighbors helped me rescue it; she and I cleaned it out, saved the shelves, and took off the door and magnetic catch. One hinge had pulled away from the door, leaving it irreparable. I saved the hardboard from the middle for another project and ditched the broken frame, leaving me with this very nice brand new empty cabinet.
It had a problem.
It works just fine, too! The shelves were not on very strong supports, but it works well enough. It's holding canned goods, with my small cookbooks on the very top--yanno, that used to be the bottom. *grin*
When I went to the hardware store, I took my time and explored, and eventually I came to an aisle FILLED with small plastic drawer-type bins.... and voila! I found sturdy metal shelf supports, bigger than the ones it came with but still fitting the same size holes. Hardware stores are SUCH amazing places! I sure like ours! And now my new lil shelf unit is perfect for tuna and beans, canned soup and fruit, and even (shhh! don't let the doglet hear) a big box of Milkbones!
