I wish I had thought of it sooner but I thought it would be really cool to make a Spring Break t-shirt. Take a plain white t-shirt and draw or write on it all the places/activities you did during Spring Break. Or if you took a trip, write the place. Mark thought it was a brilliant idea but he's already been back to school for 3 days after our Spring Break.
If you're very creative, you could even figure out how to do photos on a shirt. (I know it can be done.) Your kids could tie-dye or fabric spray paint (much easier than tie-dye) during their break as a backdrop for the written stuff.
