this is an adorable little stand up tree
While these are all adorable, my first reaction to your question was to suggest doing tiny blocks, using Rhonda's wonderful templates and instructions! What a great way to test out her methods without committing yourself to a full quilt of tiny blocks. And if you made 2 blocks, sewed faces together, turned then lightly stuffed, you wouldn't need binding! You could add a couple beads to "quilt" the layers, or do just a simple stitch in the ditch thing.
Good luck finding what you want. Be sure to show us!
