You can take any juicy green shaft and make an arrow very quickly. As soon as you take the bark off, run the shaft back and forth over a stove, gas, elect, charcoal, for about 8 to ten minutes. Don't char the shaft.
Put them up till the next day. They will dry out more, over night without checking Next day you can heat them up again and straighten them out. I've done this lots of times with summer green wild rose, high bush cranberry, willow and elderberry.
