This is one of my knitting needle cases (with my most complete sequence of needles-- 1s through 13s, only missing 11s and 6s!), and a friend gave me this Jack Skellington patch ages ago. I had never done anything with it, but I wanted it to be somewhere where I could see it often (I love the Nightmare Before Christmas).
Alternatively, the patch could have been hand-sewn and ironed on. But I liked the stitches showing :)
