This is a stack of 24 used t-shirts, with the hems sewn shut and lines drawn around the collars, waiting for Daisy Scouts to work some scissor magic and turn them into reusable shopping bags for World Thinking Day. For those of you new to girls scouting, as I am, each February 22, girl scouts and guides across the world think of each other and raise awareness of the global nature of the girl scouting movement. There is a theme for each World Thinking Day. This year, it's "we can save our planet." So our Daisy Scout troop will be saving the planet one shopping bag at a time.
