Since I have two girls (and a serious addiction to making bows) we have...a few.
Okay, 114. But who's counting?
While I realize most people probably don't have quite that many, this is still a good idea for storing them.
I painted a picture frame, without the glass or the back, and attached strips of ribbon (which you can't see in the picture) with a heavy duty stapler. I clip the bows to ribbon and VOILE! A handy bow holder. Then hang it on your wall and it also serves as frilly, girly wall art.
Of course it will probably only hold 25-30 bows. Ahem. Which is probably just right for normal, rational people.
