Those inexpensive vinyl tablecloths are good for more than just picnics -- they make great material for pillows that are easy to clean.
To make one, cut two squares in desired dimensions from a patterned tablecloth, adding 1/2 inch to each side. Right sides facing, stitch pieces together with a 1/2-inch seam allowance. Leave one side open for batting or pillow insert. Turn right side out, then stuff (if using batting pull it into small pieces). Stitch opening closed.
