It's a dog's life -- and a cushy one at that. This soft bed, suitable for small pooches, can be refreshed with a quick switch of covers. You'll need 2 same-size dish towels, 2-inch-thick foam (cut 4 inches shorter and narrower than the towels), and iron-on Velcro fasteners. Lay towels on top of each other, good sides facing. Sew 3 sides, about 1/2 inch in from towel edges. Turn inside out, insert foam, and iron the fasteners to the open side. For a neat appearance, fold that end as if gift-wrapping a box and use the fasteners to keep in place.
