Lovely leaf collages help smooth the transition from lazy summer days outdoors to life among the ABCs. Step outside and you'll find a palette of greens, reds, purples, and golds at your feet. Pick up a leaf and try to imagine what it could become--a butterfly wing, a flickering deer tail? Or think of leaves as nature's tissue paper, and cut them into appealing shapes before arranging them on a card or poster. Alphabet leaf collages make excellent classroom projects; the letters divvy up nicely so that each student can have one to illustrate.
