I finally cleaned up a bookshelf and over-the-door shelf unit today. When I finally got into it, I was surprised - they were in worse shape than I thought they'd be. So much dust! Everything was cleaned off and organized. I had a box of things that needed to be added tothe shelves, so it definitely required some sorting and pitching. Looks much better.
I still need to do a few others: the drawers in my sewing cabinet, a basket on my peg board and a bin or two, but this went a long way to making my sewing room feel cleaner and a more pleasant place to work.
