1. Print out your pattern to a size you like or to fit your paper. Transfer the pattern to the black construction paper. You will need two sides for each leaf (one should be in reverse). First cut the insides out and then the outside shape.
2. Cut a piece of contact paper and stick it to one of the two leaves. Any contact paper hanging over the outside edge then gets cut away. You should now have a sticky middle section of your leaf.
3. Tear out randomly shaped pieces out of the different colors of translucent paper and then stick them onto the sticky side of the contact paper. Allow the colored papers to overlap each other, too. Continue until the entire sticky middle area is covered. Then glue the second leaf onto leaf to cover the side you were working on. Now both sides of the leaf look lovely.
The tutorial below shows you a different project using a similar technique as this one.
