I found these at my local Salvation Army. I probably paid too much for them, but they were in great shape, had a versatile style and could be dolled up with a new coat of paint and new hardware with pretty minimal effort.
The gray paint was purchased a while ago for another nightstand project and the new knobs were ordered from Anthropologie. I primed the nightstands with a spray primer first but made the mistake of using white primer, rather than a dark one. It took three coats of paint to cover up the primer, but that might have also had to do with the fact that I was painting without a lot of light. All's well that ends well though, since they are finished and looking good. Now I just need my hubby to carry them upstairs for me.
Of course, I am already plotting on making a fabric covered headboard but that might have to wait a while...
