Have you read the Golden Compass series? In the third book, The Amber Spyglass, there's a world where, instead of having a central spine like we do, all the large animals have a diamond-shaped body with a limb at each of three corners and a head at the fourth. I've decided that must be what the TIAS is.
I have been doing other tatting as well, but it's going a bit slowly.
