Creating an open mouth in needle felting is a fantastic way to add expression and realism, especially for animals or character sculptures. Here are 5 steps to get you started;

Needle Felt an Open Mouth:

1. Form the Head Base: Start with a firm core wool shape for the head. Leave the mouth area slightly less felted so it’s easier to manipulate.
2. Create the Upper and Lower Jaws: Felt two separate pieces—one for the upper jaw and one for the lower. Shape them with a slight curve and attach them to the head, leaving a gap between them.
3. Define the Mouth Interior: Use dark wool (like deep red or black) to line the inside of the mouth. This adds depth and realism.
4. Add a Tongue or Teeth (Optional): A small strip of pink wool can be shaped into a tongue and felted into the lower jaw. Tiny white tufts can be used for teeth.
5. Blend and Shape: Carefully blend the jaw edges into the face using matching wool. Use a fine needle to sculpt the lips and refine the expression.
