RugosaB, your six sets of upper cabinets stacked three high is one of the very best options for storage, IMHO. It will provide accessibility without lifting heavy totes, protection against light and dust damage, neatness for storage, and flexibility for storage methods. Congrats! In fact, I wish that I had done this a dozen years ago when we were remodeling our home. I hadn't been sewing that much at the time and didn't even consider having my own sewing area. Dumb, Dumb, Dumb on my part....
