I've made a mini top hat yesterday. It's made of foam and light cotton fabric, both sewn and glued.
The first picture shows the newest hat I made, decorated with velvet, tulle, feathers and lace.
The 2nd picture is an older one I made for a friend, the 3rd one is one of the hats without the decoration.
