Sweater Delinter Ball

Every get those balls of lint on your favorite sweater?  The delinter ball would be a plastic ball with specially designed tear drop shaped holes in it that you would put in the dryer with your sweaters.  Then as the ball tumbled with the clothing it would gently rake the surface of the cloth catching those pesky little lint balls.  At the end of the cycle you would have the delinter ball with all the fuzz inside it.  Just empty by uncapping the screw top lid and your ready for your next batch of sweaters.
