Thats mine.
I used half a yard of fleece, i cut out 2 circles, about 12 inches diameter, from a large plate as a template, one with soft fleece, another with durable polyester blanket.
Then i used the remainder, and i cut it, so its 3 inches longer than the circumfrence of the circle. I put stuffing, which was peices of leftover poly-blanket, cut in peices the siz eof my hand, and i put it, and i left a spot for the entry. Then io sewed ti toghether, and i did the same with the circle. I sewed both parts togheter afterward. Then i cut the section out,a nd sewed it toghether
