1. Dab a bit of glue onto the back of a leaf, and attach to a piece of construction paper (we pretrimmed ours to fit a 5"7" frame).
2. Tape the paper to a sunny window, with the leaf facing out. Leave up for three to four days, until you notice that the paper's color has faded.
3. Remove from window and gently peel leaf off to reveal the print. Frame and hang.
