The board is made up of two large squares of felt, an oval piece of felt for the face, and lots of different facial features and hair-dos cut out of felt. The nice thing about felt is that it sticks to itself, so fasteners aren't necessary.
Faces can be put together by the child to match an emotion, or by the adult for the child to guess. Emotions can be simple, like a smiling face, or complicated, like the anxious fellow above.
Faces can be customized to represent the child or their friends and family to make things more relatable. Because the pieces are made from felt, this can be safely used with fairly young children. Older children may also enjoy using this, especially if some form of current fashion or video game is used as inspiration for the felt pieces.
