I use a small section of surgical tubing instead of coils. The tubing allows the thread to cinch down securing the flashabou. I use a fly tying bobbin, and I use two one package per skirt. I use a small section of wire with a loop on one end to slide the tube on, then clamp the wire end in the vice. Wind the thread on the tube, grab half the package of flashabou and center on the tube and wind and cinch thread down, turn skirt to bare side up, apply rest of flashabou and repeat. finish with a few half hitches and apply superglue to wraps. Mine last many muskie thrashings with no shirt loss.
