I was searching for inspiration to make a lunch bag, and I run into Blissful's lunch sack idea.
I have to say hers are 20 time cuter than mine, but I'm still pleased with my work.
It's big enough for myfood and juice containers and a small water bottle. (pic 3)

I used some fabric I had brought some time ago and old sweater for the linning. I guess it's better to use interfacing to have a more sturdy bag, but I didnt have any at the time.
I liked the idea of using two buttons so I can adjust it for bigger or smaller containers.
