    * Cardboard

    * Box cutter

    * Ruler

    * Scissors

    * Hot glue

    * Hot glue gun

    * String


    # Cut out cardboard pieces for arm, hand slot, and back support.

    # Use a ruler to bend the joints in the cardboard hand.

    # Cut bendy straws into smaller pieces. 20 small pieces that go in between the joints. 4 pieces that have the bendy part of the straw. 4 pieces that are twice as long as the pieces in between the joints.

    # Hot glue straw pieces onto front of cardboard hand.

    # Poke a hole through the cardboard for right beneath the thumb and continue hot gluing straw pieces on the other side of the arm.

    # Cut the big rectangle piece into an “H” pattern. Fold cardboard pieces inward and hot glue the edges. Stick onto cardboard arm.

    # With 5 pieces of string, thread each one through the corresponding straw on each finger. Tie the ends and tie a finger loop at the bottom of each. (Optional: add a drop of hot glue to the knot)

    # Hot glue longer rectangles together and use more hot glue to stick to the back of arm.

    # Decorate if you want to!
