I don't think the really small needles are typically made in wood...I *think* brittanyneedles.com has 5" DPN's down to 0 in wood. I love the brittany's I have in 2, but I have broken some of them. Not sure how well they'd hold up in a 0, but since you knit loosely they should be ok. Under a 0 all I've even seen is metal. I think they might have to be metal at that size for strength.
