Here's a tutorial from Martha Stewart on repurposing an old plate into a pretty little mirror.
This is especially great if that particular plate has any imperfections, but you can't seem to part with it. Doesn't the ribbon give it such a nice touch?
If purple is your color, I'll be bringing a handfull of pieces donning the hue at this weekend's Market Day Iowa! I hear it's pretty hot this season;) Hope to see you there!
