Measure the length of valance that you want to cover. Now decide the number and size of leaves you want to cover this length. You can also use two different shades of green (light and dark). Use one shade for larger leaves and another for smaller ones. The small ones can cover up the gaps left by the large leaves so that there is a filling effect.
Now that you have decided the size and number of leaves, use the paper sheets to make leaf patterns. Use a pencil so that you can edit the patterns to have perfect leaf shapes. Cut out these paper patterns.
You will need two paper patterns; one for the large leaves and one for the small leaves. These two patterns can be used to cut multiple foam leaves.
Place the paper patterns you made in the previous step over the foam sheet. Use the scissors to cut out the leaf forms from the foam. Take the valance rod off and place it on a flat surface like a table you can work on. Practice the pattern you want to create without glue until you are sure about the permanent look. Attach the leaves to the rod using the hot glue. To give a more realistic picture, wind the rod around the leaves to create an impression of twines and stems. Put the rod back on and it is all set.
