I've made over 200 of them. I quilted 5 straight lines so that the batting wouldn't shift (used lots of straight pins to keep the fabric from puckering). Used pillow panels (did some machine quilting on them for dimension) for the pockets on the quick ones. Made pieced squares for special pockets that were given as gifts.
Using a heavier batting will give you a fluffier pillow.
Haven't made one in years, but still get requests. They are a quick and easy gift and are usually well appreciated.
