Sliding the Fibers into the Bag

Mary helps the felter put her finished layered fibers into a bag, carefully laying it out with the pretty stuff on top. The bag will allow for a flattened felted piece. The next step is to wet the fibers with the pre-mixed mixture of shredded dove soap and water -- a gooey, but clean, binder. So what happens next? The water and soap release all the tiney barbs in the natural fibers and cause them to migrate around and re connect with other fibers in a new matted form -- that's felting, in a nutshell (or a baggie), the way I understand it.
