Where to buy cargo netting?

Anyone have suggestions on where to get light-weight, non-industrial quality, cargo web netting? All I've been able to find is high-end commercial stuff (much to heavy-duty for my needs) or automobile trunk/hatch stuff (much to wide -- I didn't see a way to cut or adjust).

Does this come in rolls or some other application that is cut-to-fit?

I'm just looking to make cover some small shelves, make pockets, etc., in sizes such as 12"x 6", 24" x 10", and so on... really small stuff.

TIA!
