While this care package isn't quite eco-friendly it is green. Here is another package I'm sending this week to my brother-in-law out on a mission. He is a brand new missionary and there's a tradition of calling the new ones "greenies" so I'm sending him a green package. I spray painted the inside of the box green and then threw in plenty of snacks, candy, some Irish Spring soap, a toothbrush, some post-it notes, a green slinky, and a small green picture album with pictures from his last few weeks in town.
I threw this on the top when I packaged it so he'll see it when he opens the box.
If you could get a colored package what color would you want? I'd want purple. Wouldn't that be fun?
