How about embroider and tear instead. I finished knitting the mitts for Daniel earlier this week and finally took the plunge to do the embroidery. Past attempts at embroidering on knitted fabric have been less than satisfactory but I'd seen a tip to embroider over tissue paper that I wanted to try. I found an image he liked in a size that was appropriate and printed it out then traced it onto tissue paper (making two copies, one for each mitt). I basted the paper onto the mitt with a sewing needle and thread then used a sharp tapestry needle to embroider. Once it was all done I ripped out the paper leaving the embroidered design intact. Weave in the ends and they're all set. Mission accomplished!
The pattern is similar to previous fingerless mitts I've knit but I've made it just a bit larger for a better fit and the ribbing is easier on the hands as well.
