It happens to be Wednesday and I happen to have a tip so I thought I'd jump in the fray here. Don't forget to check out Rocks In My Dryer for more great tips.
I recently reorganized my yarn stash. My biggest problem is that I have a lot of yarn and sometimes forget what I want to do with it or forget where I put it. While I still have boxes in the closet I have also decided to reorganize by taking projects and their pattern and putting them into bags and hanging those bags on hangers in the closet. This way when I am looking for a new project or want to work on a project I started and stopped I can go through the bags. Makes the closet neater, keeps the projects neatly organized and definitely works for me.
