I make my own grocery bags and have been doing it for years. I give them as gifts and usually make mine out of left over material or a sheet. I took a Target plastic grocery bag and cut it in half to make a pattern because I think Target has the best size available. But, for the rest of the world who would like to know how to do it right, here is an awesome tutorial. I also make these bags for children and their belongings. Gabe has one in the car full of things to entertain him. Enjoy!
