I was keeping them in a large wardrobe that I had built shelves inside of, but then the shelves sagged really badly. So, I picked up a large plastic tool cabinet at Home Depot that's shelves were designed to hold up to 600 lbs. I also have overflow boxes of jars stacked inside of two closets.
I worked with a contractor on designing wall cabinets for the pipe room when we were building two new rooms onto the house, but once the contractor got finished with the rooms, he started dicking me on the quotes for the cabinets as well as a wooden fence. Needless to say I fired him, and I just left the project half finished. I will have to finish it myself this summer. So, for now I just deal with the large tool cabinet and unusable closets.
