The kind you can buy in Tesco with ladybirds on?
I saw someone yesterday while we were at Legoland with one of these bags with something along the lines of 'Don't buy plastic bags,use me & raise money for (name of school) & save your planet'. This was written in a sort of sqiggly line & looked really effective. I asked the woman if she knew where they had come from as I think it's a brill idea for a fundraiser for School. She had bought it from their School but didn't know where they had had them made. It was St. Mary's School in Washington, Sussex I think she said, anyone know anyone that goes there?? I have Googled jute bags but can't seem to find anything that would be suitable. I am on a mission now to get some of these bags, I'm sure they would sell well at our School. If I don't have any success, I might even e-mail the School, would that be cheeky??
