I made this lunch bag for my dad for Christmas but I forgot to get a picture of it before I left for home. I have been waiting for a while to get them and they are finally here. I took my dad with me to the fabric store to help my pick out the fabric that he wanted (and because I thought it would be fun to see him in a fabric store).
The outside is a home dec. weight cotton poly blend and the inside is a nylon type that you might see used for a tent. We picked the inside fabric because it was semi-water resistant and it was thick. My dad just really liked the outside fabric.I made it taller (12in) than your average lunch sack because he wanted to be able to fit his water bottle in it and still close the lid. Other wise it is the same dementions as his old lunch sack. I also lined it with some stiff interfacing on the front and back but then put lighter weight interfacing on the sides so they would fold easier.
