Where can I get brown packing paper mesh?
When I want larger volumes of packing material, I tend to look to two sources:


Self-storage facilities. A lot of these places offer boxes and other packing/storage material and may offer cardboard options as opposed to traditional bubble wrap.
Self-moving companies like U-haul, amongst others, who can supply a lot of the basic packing and storage material for a move.


Beyond that, office supply like Grand &amp; Toy, Staples, etc. would be next on my list. Actually, given some convenience, they might be first. :)
