Saving the Sheep

I think I've came up with a way to save those poor, innocent sheep and not a moment too soon, either, as we've had snow today. I checked the quilt books when the polar bears weren't looking, and there's something that can be done with wool called felting that I believe will render it useless for the polar bears' purposes. Now I just have to figure out how to convince all of the sheep to felt themselves at once. Do you think if I mail them the instructions on felting wool and a large box of detergent, that will be enough?
