www.allfreesewing.com has lots of free patterns for any size tote bag and purses.I shop at a grocery store here(Aldi's) that does not furnish bags ,so I made my own.when I buy groceries,after i empty them, I fold them and lay them on top of my purse , and they go back in the van,as I do. I had a flannel backed tablecloth that I used to line some of the bags.Makes the bags very strong.
