Here is how you make your own. Get a placemat. I bought this one at Kohls. They have a pretty good selection of placemats. I always see random placemats for sale and now I know what to do with them! Snatch them up as you find them!
Get your seem ripper and rip about a 4″ section of the seam – enough to get your hand in.
Using your favorite fiber-fill, stuff the opening until it is the desired fluffiness.
Pin the opening closed and sew along the edge of the pillow. My placemat had a double seam, so I sewed 2 seams.
Done! This placemat was kind of a stiff-durable fabric. Not the kind of pillow I would want to watch TV with, but perfect for my bench on my porch!
