Clay is always a popular medium and adding pinecones and beads was just the touch we needed. I used home made salt/flour clay as a base and had everyone make a fish with the details they wanted to include. We next took the individual pieces from pinecones and dipped them into a little white glue and inserted them into the clay to form the scales on the fish. We added glossy green beads for eyes and took them home to dry for a couple of days.
We could have painted them before or after putting on the pinecones but wet clay is unpredictable and can get gooey. Some of the group will paint them when they dry at home. Easy enough for all ages.
