Organizing a Multi-Use Space

I am generally pretty organized. Ask me for something & I can usually find it within one look, 2 at the most. I can proudly say that I rarely lose things downstairs. And then there's the studio upstairs....not my finest achievement!
The studio is also a storage room, access to the attic, exercise room and often a laundry drying room....a not for public viewing space. It really got trashed during and after the shows in the fall and then the holidays came and all that stuff. The holidays ended and the decorations MUST be put away so the craft items, remember I said this was the STUDIO, were still scattered. Finally, mid-January I purchased some craft item and when I went to put it to use, found I had 3. Okay, this has got to stop....buying what you have is ridiculous.
I spent over 7 hours within the last week cleaning and organizing. Throwing out and consolidating. Buying more bins and drawers. Paring down some materials and noting I needed more of others. The hardest part was finding a particular supply or button or piece of paper and thinking "hmmm, I could make a..." and the cleaning got brushed aside. Then this weekend, I had an off-line sale of this button jewelry box~



I realized that was the last of the 7-8 boxes I had made. Off to the craft store for 6 more boxes. About 10 minutes ago, I started to work on a previously untouched cabinet up there. What did I find? Of course, 4 more boxes.
Moral of the story: Keep like items together and KNOW where you put them!!!
