Tracy, a few yours ago someone posted pics of a simple jig for hand fletching shafts. It may have been Jamie. It is basically a small piece of cardboard(or another similar material) with a shaft size hole in the middle and slots radiating out at the appropriate angle(ie. 120 deg for a 3 fletch). This jig holds the feathers as you wind the thread. There was also a jig for holding the shaft while working on it.
Do a search to see if you can locate that thread.
