A rope bracelet - reminds me of making friendship bracelets back in the day. My right second toe used to go numb because I'd hook the end of the bracelet over it, and then knot embroidery floss for HOURS.
Also take a t shirt that covers the pillow with at least inches on all sides. cut strips and tie together. for scrunched edges and not shaggy look. turn pillow case inside out after the side is tied. tie the tight. no sew pillow!
