I posted a wee while ago about making reusable shopping bags in the shape of a plastic bag, and have recently submitted it as a business proposal as part of my course at polytech!
Here is another prototype, this time made from white cotton with a screenprinted paper doily and the words "i'm good to the earth"
I would love to get the chance to produce some for sale, though free time is lacking at the moment already...
might have to fit it into a project somewhere :)
