I have 2 yards of black, 2 yards of stars, a half yard of each zebra, 2 yards of batting, and a half yard of that fluffy white stuff. I am wanting to make a fleece blanket with additional sides to tuck over the walls of my c&c. I also am making a kitchen area out of leftover coro. My cage specs are 3x5 and the kitchen will be 3x1 1/2 grid lengths. Do i still make the fleece blanket fit the entire length of the cage or just to the tip of the removable kitchen? Also do the side pieces need to be doubled up or can they be single layer; do i make the bottom first or attach and sew all at once?
