When I make a sleeping pad for my dogs or cat I make it 4 times bigger than the area it's intended for. That way I can fold it in quarters, which makes it nice and thick, and as it picks up their shed fur I can flip it and fold it and refold it several times clean side up before having to wash it. I have to run it through the dryer on air fluff with a softener sheet a few times to shake out the fur before putting it into the washer. I swear they shed so much I could build a whole new dog with the hair I sweep up!
