How do I make a food safe cloth sandwich and or snack bag?

Question

I want to ditch the ziplock bags and make sandwich and snack bags. I was going to line the bags with plastic but I realize that this might not be the safest way to go. What materials would be safe and are there any patterns out there?

Answer 1

other than reusable containers this is the only thing i have found.
