Article: You can mix and match different prints, colors, and textures of fabric in order to create a comfortable bed that matches your home décor.  Make sure the fabric is easy to clean and/or able to be put in the washer. Faux fur, fleece, terry cloth, and cotton are good choices. You can also use old curtains. You can use pillows, old cotton clothes torn into strips, polyester stuffing, chopped foam, egg crate mattress toppers, or even scraps of different types of fabric you might have lying around the house. Make sure to use non-toxic material that won't harm your dog if s/he chews up the bed.
