i made this puff patch in the early 90's. had lots of help stuffing it! the front is mostly all polyester scraps & silky fabric [used for lingerie]; the entire back was pieced together & sewn onto the front like you would sew a pillow case, turned right side out & handsewn shut. the flannel back is tied to the front w/ embroidery floss. it has been washed several times & line dried...still in pretty good shape!
