I have used two of these for many years. One is for scrapbooking supplies....and lightweight is the key word here.
One is for a portable sewing 'basket'. When Mom moved in with us, we found ourselves with about 4 sewing baskets/boxes. She spent many hours combining all the sewing supplies and organizing them into this multi drawer unit. Happy memories when I can go to the unit and find what I want because Mom had put like things together. Organization was one of her strong talents. Just wish we had had the time to enjoy it together.
The dowel stick idea previously given would be worth the time to keep the drawers on track.
The unit has endless possibilities.
