For this Cheshire Cat costume I started with making the face as wide and big as the character in the movie. Materials used are: fabrics (purple and pink), foam roll, pillow stuffing for the tail, pretty much everything was sewed and put together with my designing and cutting and my mom’s sewing skills!
We cut strips of purple and sewed it on top of pink fabric suit. The tail is stuffed with batting and is a little heavy but I needed it big and soft like. We attached nylon string so it could be off the ground and held up. The face was made from some foam and fabric cut to mimic the 3D shape of the cats outer area. The ears and top of head are flat but looks great from the front view. We left a slit for the eyes between the nose and eyes of the cat.
All and all we spent about a week and a couple of days on this thing. My wife had her heart set to be the mad hatter so I had to match her of course.
