Like I said like last week, I do not have a specific art "box" that I let D create out of. I have recently remodeled my craft closet to make it more kid-friendly so that D can select his material without totally destroying everything. In the craft closet, I also keep my "I-am-saving-that-because-I-am-sure-that-I-will-use-it-for-something-box", hence the empty Dora yogurt cup. This day D created a rocket out of construction paper, LOTS of tape, aluminum foil, and yogurt cup.
