Well, folks, this is how I store my supplies, mats, rulers, etc.: Since I have to cut out and sew on my dining room table, I keep all my sewing/quilting things in the closet in an upstairs den/office. I put everything helter-skelter on the floor, on some shelves, in a drawer and in some craft totes. Then when I need them, I rummage through everything and swear and sweat. Then I promise myself to organize everything nicely soon and trudge downstairs with the mats/scissors/rulers/cutters/thread I need and when I'm done sewing for the day, I carry everything back upstairs and toss them in the closet again.
Pathetic! I'm so envious of the wonderful sewing rooms and spaces pictured!
