I found an old wood door in an alley on the way to work one morning this summer. A little sanding spruced it up quite nicely. It's still pretty rustic, but we like that around here.
Then on my way back from Bumbershoot, in Seattle, in September I bought a weird narrow table at a Goodwill south of Bellingham, for $6.99. I bought it for the legs (and the brackets that were included), thinking that they would be just the thing to turn the old door into a display table for the shop.
Here are the bits and pieces (the narrow board on the floor was the table top - odd),
And here is the door as a table! (sanded side as the top)
And here's a shot that I just took on my phone of the table in action, nicely displaying our kids clothes.
