well if you knit them on circs i think you are going to have to knit for small diameter knitting. basically the smallest circs that i have ever heard of is 12 inch. trying to wear a pair of mittens that are 12 inches in diameter could be difficult. http://www.knittinghelp.com/knitting...ed_techniques/
there is the link to the page with the magic loop and two circs methods though...you can certainly try those out!
