The best leaves for this project are still attached to the tree. Find leaves that are turning colors but aren’t completely dried out. You need one leaf for each color you will paint.
Press the leaves in the pages of a heavy book. Leave overnight.
Remove leaves from the book. Look at the underside of the leaf. Brush off any debris, pollen or dust that may have gathered there.
Fold a piece of construction paper in half.
Hot glue the front side of the leaf to the construction paper so that the underside is facing up. The underside has the veins and lines of the leaf, the front side is smooth.
Using a paint brush, paint the underside of the leaf with a generous amount of paint. Be careful to paint only the leaf and not the construction paper it is glued to.
Using the leaf as a stamp, press it down carefully onto the white paper. Hold it in place and gently rub the construction paper so that all areas hit the white paper.
Carefully remove the stamp and repeat this process with your other leaves and colors.
