Love this idea. We are in a wooded area and my residents would enjoy using nature as their materials. We have gotten twigs of the trees before - or broken ones on the ground - and glued them on heavy paper to make a branch. Then cut out bird forms, colored or painted them and glued them to the stick/twig. It made a neat 3D effect and each one was different because of the shape and size of the twig. We also gathered rocks and painted them making our own pet rocks and talking about that fad/craze
