When Barbara Becker Simon was in L.A. a little while back to teach a workshop, she shared one of the books she used to get inspiration for textures. "Art Forms in Nature" by Ernst Haekel gives a wonderous look into the microscopic world of all kinds of organisms.
I was so mesmerized by some of the images, that I was compelled to create a tiny creature called a Diatom. Actually one of that species.
I've listed him in my Etsy shop today and invite you to go take a look. I think it's really lovely and may be inspired to design a whole new line of tiny creatures.
