If you break a needle, whether plastic, wood or bamboo... DON"T throw it away. Those short pieces, when sharpened at both ends, become great little double-points for knitting the fingers on gloves. Then you'll be wrestling with a hedge-hog instead of a porcupine. I have had my share of experience with snapping needles in half, or even just the first two inches off the tip.
Since I'm a cheap S.O.B. I also came up with a cheap way to store my Lilliputian DPN's. Plastic M&M candy containers keep my short DPN's corralled, as well as straight pins, sewing needles, safety pins, and who knows when I may need a snack while knitting (melts in your mouth, not in your hand) that won't make a mess. I'll put a pic in the gallery and you'll get to see what I mean.
