I looked around my pinterest sewing board and found a pin that was perfect! Bijou Lovely's Market Tote tote is just great! The instructions are very clear and simple. I referred to another pin, by Sew La Vie and her Market Tote, where she used heavier fabrics and made some alterations.
This is a great size for lugging things around and it fits nicely over your shoulder. I can't wait to send it off to my mom, although I hope I can pack it so that it doesn't get all wrinkly..!!
