So, my ballwinder is my favorite tool, along with my niddy-noddy; then my swift. In a pinch I'll use a nostepinne -- the ballwinder is basically a nostepinne with a built-in crank. All that said, there are "human" or inexpensive equivalents. The thumb makes a great nostepinne (just don't wind too tight!), the fore-arm is about a 2-foot-skein niddy, and the lower leg (wind over your knee and under your foot -- shoes off! -- with knee bent, while sitting) is a 4-foot-skein niddy or there-abouts.
