Reusable Shopping Bag Challenge

Reusable shopping bag challenge: Someone showed me the smallest foldaway shopping bag – it could easily be carried in your purse – or maybe even attached to your keychain? – so it wouldn’t be left in the car when you get to the grocery…very thin, light, and strong fabric. The ones you can see on these websites

are good, but not so tiny – does anyone have knowledge of a better one?

I would love to see this problem addressed in La Manzanilla, a beautiful little beach town with a major litter problem.
