4 pieces of scrap fabric (see below for size)
2 pieces of fiberfill the same size as your fabric
Embroidery floss
Cedar (for dog mat)
Catnip (for cat mat)
Velcro

            Look through your scrap material for two pieces of rather tough wearing fabric. Denim or corduroy would do nicely. In fact you could use a piece of denim for one side and a piece of corduroy for the other side of the pet mat. Depending on the size of your cat or dog, cut the material to the following dimensions:

            20” X 25” for a small dog or a cat.
           
            28” X 35” for a medium dog.

            40” X 50” for a large dog.

            Of course, you can vary the size to suit your needs.
            Cut two pieces of fiberfill the same size as your fabric squares.

            Place fabric right sides to right sides and stitch all around the material leaving an 18” opening in the center of one of the long sides.
            Turn your fabric right side out and insert the fiberfill one piece on top of the other. At this point you can anchor one section of  fiberfill to the top piece of fabric and the second to the bottom piece of fabric by tying off sections with embroidery floss as seen in Quilting – the first archived article.
            Make a pouch that is 4” smaller then your pet mat from any scrap fabric. Fill this pouch with cedar shavings and sew shut. The cedar will help to repel any fleas and will add a wonderful perfume to your pet’s coat. Cats will love their pet mat if you add a small pouch of cat nip instead of the cedar. 
            Place the pouch into the center of your pet mat. Now sew a strip of Velcro to each side of the mat. This will make it easy for you to change the cedar or catnip pouches as needed.

        If you use a pet carrier these mats, made to the dimensions of the carrier, make travel much more comfortable and pleasant for your pet.
