Bamboo "skewers" or how ever you spell the sticks you use to grill chunks of food
Grocery store, Kitchen store, Target, Wal Mart ... I carry a needle gauge with me and measure EVERY round stick I see. They are also easy to sand down to a smaller size. I have made several dpn's and my Kids Knit group just finished making some VERY CHEAP # 5 straights to use for bookmarks!
