So we went to work looking for containers and bags in our house (here's an older version I made when Faith went camping at NASA back in Texas). We came up with a few recyclable containers, and I did have brown paper bags (which I bought for a scrapbooking project, not lunches). I did have to suck it up and buy a 6 pack of water bottles because we didn't actually have any options for disposable drinks and I didn't want to risk a stainless steel bottle being lost.
This would be Ben's lunch. I have it packed in a washed out container from blueberries He had a black pepper turkey and colby jack cheese sandwich on multigrain rounds. After slicing it to fit in the box, and adding a raisin granola bar, I discovered it kind of looked like a mushroom, so added a cheddar butterfly with muenster accents to it (the antenna is a carrot sliver). Ben also had a cutie orange and a big strawberry.
For Faith, I had a styrofoam container leftover from a restaurant the other night, so I washed that out as well. Faith has the same general foods as Ben, but added carrots and took away the orange. Her sandwich is decorated to look like a bear because I couldn't figure out what else I could see in the sandwich and it was 11pm when I made it.
And brown paper bags are boring, so I drew Perry the Platypus from Phineas and Ferb on both. Faith had him as Perry and Ben had him as Agent P. I am typically not an artist, but I can draw flat characters halfway decently.
