I used to collect "Curlys sticks" to make walking sticks out of. Those are the saplings that grow up in a mass of vines and the vines wrapping around them causes them to grow in a spiral fashion. They were usually dog wood, sassafras. redbud or hickory. I wouidl collect them in the winter while hunting after a fresh snow. I could really see the curly trees stand out against the snow. I think I still have some blanks in the garage attic.
