Now it is a bit draughty, I've started thinking about knitting some mittens for my 13-month-old ds. Last year I just did little bags with a drawstring for the wrists but I am now wondering if he might get really annoyed about not be able to use his hands, should I knit a thumb separately or is it just too much faff to put on a wriggly hand? And does anyone know of any good patterns for them?
