Yarn was from Leah (drawing on UFO blog), handdyed by her. I think it's wool/angora, it's a "gimp" type of yarn, one ply thin, one thick. Spears loom is the more modern one with a plastic heddle, the small size with the warp hanging off the back rather than rolled on a warp beam. Cute execution, novel in its way.
The wool appears to have been a superwash -- no noticeable shrinkage in finishing. I gave up on a "gentle fulling" and threw it in the machine -- no felting to speak of. It did get a fair bit shorter, though.
