Organization: Hooks to store chairs or bags

While browsing through the Ikea catalog, I saw this picture tucked into one corner.

While it's a great way to store folding chairs (as shown), I think it would be even better for our collection of shopping bags.  They're currently sitting inside another shopping bag, and it's kind of a hassle to get them out or put them away.

Each hook is 6" long, so I calculated that it could hold about 30 bags (five bags/inch).  I want to get two or three so I could organize the bags by size.
