One of my favorite organization tools that I use in my home office would have to be my shutters. I found them at the Metrolina Antique Show in Charlotte. They were 2 for $5, and were originally navy until I spray painted them white to match my office.
They are great for keeping important references close-by my desk without creating holes in my wall. Additinally, they allow me to maximize 6 feet of vertical space and are easily moveable around the room.
On one, I have:
-frequently used coupons for restaurants / activities that I need to remind myself I have (or I will forget to use them)
-inspiration – things to be grateful for, favorite quotes/inspirational photos
-upcoming events clipped from Charlotte Observer and other magazines
On the other, I have used Stick and Store baskets to hang on the grooves in the shutter and I organize plans for upcoming travel.
What other uses do you have for old things?
