You will need:
A collection of leaves and flowers.
Two sheets of clear contact
Two plastic bowls or plates
After you’ve collected the leave and flowers put them in two bowls, peel back one piece of contact and hold down so it doesn’t roll or shift with the two plates.
Allow child to decorate. Add cut up cellophane or glitter if you wish.
Peel second piece of contact and carefully lay sticky side together with the other.
Now tape the contact sandwich to the window.
The flowers will go brown after a few days.
