In our last apartment we had curtains in his office with a pattern that resembled an entomologist's collection: lots of birds, butterflies, plants, etc. Birds and plants are a hobby of his, so he was disappointed when he realized his new office wouldn't need curtains due to the massive skylight over his desk. So we decided to use them to cover up the ugly old Ivar shelf with all his messy-organized teaching materials. We added a few screws (ie pegs) to the unit, and thanks to these little curtain hooks, it's easy to close it up when you want.
Sure, it's basically a wall of fabric - but it's primarily his office, so as long as he's happy and the shelf is covered, then I'm happy. The best part is that we were able to use things we already had on hand. A bonus is that our printer is also in there, so it's not getting dusty anymore!
Stay tuned for another office project - this time in my office!
