I do kind of the same thing. I keep the mesh bags from a sleeve of garlic bulbs and from bags of onions and re-use them. I hang onions, potatoes, etc. from the edge of shelves out in my garage during the cooler months. My garlic hangs off of the bag, wrap, and paper dispenser on the back of my pantry door.
When I have a big flush of tomato harvest I use a big wire rack with paper towels either out on a table in the garage or on the (seldom used) dining table with newspaper underneath in case one gets nasty. It keeps some space between them and air flow all around.
Those really fine mesh tubes that multiple bulbs of garlic come in make a great sack for putting small parts in the dishwasher. Drop the little parts in, tie a lose knot and push part of it over a tine or two in the upper rack. Works great, been doing that for years.
