Furring, adding ears, and more EL wire! This was literally the day before Vancoufur.

The ears are made of fun foam glued to a double-layer of wire mesh so that it can hold its position and curvature. I actually ran out of fur by this point and was using small random scrap pieces so the ears actually used multiple pieces of fur - some gaps are visible up close but I think the long pile does a decent job of hiding it. Next time I'm going to get double the amount of fur I think I need!
