If you have access to a scroll saw you can cut them into any shape, drill a hole and hang on Holiday tree with a ribbon. I'm thinking more nature themed because they are wood grained, like mushroom, birdhouse, bird, chipmunk, acorn, beehive.
Speaking of beehives,(and OT) we topped our tree last year with a rope beescape beehive, bought those packages of rotating things you plug into the mini light string, bought 20 little bumblebees which we attached to the rotating things with long wire and had the bees continuously flying around the hive on the top of the tree. Man, I love nature!
