For sofa cover I highly recommend Orvis. We have an Orvis sofa cover, throw and several dogs beds in the same material. They wear well and wash well, with no shrinking or fading. I'll link the exact ones we got. We have the Brown Tweed fabric. They aren't cheap, but worth the price. I take them to the laundromat to wash in the larger machines. Dry on low/med because of the non-slip backing.
