So, a pipe in the kitchen sprung a little leak. Nothing major, and an easy fix. However, it was enough to damage a few of the ceiling tiles in the basement--especially in my studio. Once I cleaned and bleached away the mildew (yuck), I had a choice to make: put them back clean but stained, or treat each tile as a 22" square canvas.
I don't think any ceiling tiles in the basement are safe...they're all blank slates crying to be altered!
