The head and body of the needlefelted rabbit are shaped from egg shaped sections of wool roving. Take a roughly 2 inch ball of roving for the body (for a 1:12 scale rabbit) and roll it between your palms to form a rough egg shape. Use a sharp felting needle repeatedly pushed through the wool, to shape the roving into an egg shape with a narrow rounded end. If you have never needlfelted before, work your needle through your ball of wool, poking it more often through the end you want to be narrow. The more times your needle travels through a section of wool, the more densely packed that section will become. Use your needle to 'sculpt' the wool roving into the shape you wish by compacting your wool roving as you push the needle through.
The narrow end of your egg shape will be the head end of the felted rabbit. When you have the body roughly shaped, take roughly 1/3 the amount of roving you used for the body, and form a small egg shape for the rabbit head. The head should be no more than 1/3 the length of the body. The narrow end of the small egg will be the nose of the rabbit.
