I use a piece of piano wire from a hobby store for the mandril. Its the sort of thing that the radio control modelers use. I cut a piece about three inches long. DO NOT try cutting it with a cutting pliers because it will chip the blade. Instead notch it with a file and snap it (Be sure to wear safety goggles). At the end of the wire, I wrap a thread nub and glue it with head cement to keep the tube on the mandril. I then put it in an old drill chuck that I mounted on a stand or you could even put it in a working hand drill. I use dollar store "q tips" to tie on. I have them in white, purple, green and blue.
It is that simple!
If you have questions just ask.

" Fishermen, hunters, wood choppers, and others,
spending their lives in the fields and woods,
in a peculiar sense a part of Nature themselves,
are often in a more favorable mood for observing her,
in the intervals of their pursuits,
than philosophers or poets even,
who approach her with expectation."
Henry David Thoreau
