I keep my walking foot and BSR in their original boxes for protection, but all the other feet hang from slots in the accessory case that came with the Bernina. The case sits upright on a table beside my machine (along with a gajillion other sewing-related things, including oil, seam rippers, scissors, etc.) I haven't seen any cabinets like this (with slots for hanging the feet) for sale, and it does take up room on the table, which you say you don't have. Is it possible you could use floor space under or beside the machine for a little cabinet to hold supplies?
