The old skull and crossbones, not necessarily Halloween themed you might just have a little pirate on your hands, but a nice little knit all the same. Make sure you have a few 1 to 2m lengths of both black and white yarn cut before you start intarsia-ing. It will make it easier to incorporate new sections as you need them.
