Here I made the first set of ears out of some foam interfacing, floral wire, and fake suede glued to said interfacing (SUPER 77).
I just stitched the interfacing to the floral wire.
It worked pretty well!
Here you can also note that the ears are just a bit too pointy at the tips.

TRAGEDY!!!
Nah, I realized that the head was a bit too wide at this point and just, cut it in half.
It went back together just fine after some fiddling :)
I then patterned and sewed up the ears.
At this point the ears being too pointy was so kindly pointed out to me by someone you can say is very close to the character ;)

I had also sewn up most of the upper teeth at 3 pieces per tooth, bringing the new total to 243 fabric pieces, 4 foam pieces.
