I have a few tool boxes that stack on top of each other. And it will amaze you how easy it has been to fill each with the same notions. All those pesky things that you were just using that wandered off on their own-that as soon as they are replaced they reappear. I now have 3 tool boxes that are very handy to grab and go. Whether its only the living room or if I want to go visit and take some hand sewing with me.
