I just love these miniature artworks by Portland artist Alexandra Peterson! She draws the picture, mounts it on wood, then seals it with "encaustic", which is a type of varnish she makes herself.
My encaustic media is a carefully controlled combination of all natural beeswax and damar resin. Damar resin is from trees that grow in the East Indies. When melted and mixed with the beeswax, it produces a harder, more durable material, with a distinct luminous quality.

Peterson is also giving away one of her drawings at her blog. Link
