Just a "heads'-up":
We hope to have another Leaf-themed post card swap this fall. Now might be a good time to gather some, freeze some (Yes, you can freeze them between sheets of waxed paper or foil!), or press them in old books before they start falling off the trees and wither or curl up (as ferns do).
Fresh leaves work well for painting impressions, especially on the Gelli printing plate. For collage the flattened, dried leaves adhere better to paper backgrounds, especially if covered with a layer of matte gel medium.
