Get ready for the cutest tea bag holder ever.
Body: Roll a clay ball about an inch wide. Roll the side to elongate to a pear shape. Bend the 'neck' down. This is the head of the mouse.
Hook the shape onto the rim of the cup.
Ears and nose: Make a small, flat disk shape. Fold in half, then cut in half. Attach to the sides of the head. Roll up a small, pink nose and attach to the tip of the face.
Eyes: Poke the sides of the head with a toothpick to make the eyes.
Tail: Roll a very thin piece of clay and place it in loops along the back of the mouse for the tail.
Carefully take the mouse off the cup.
Place on top of a cloud of polyfill on a baking sheet. Bake at 260F / 126C for one hour. Keep the room well ventilated.
The polymer material will still be rubbery and flexible and will fully harden as it cools.
