Looking good!
Like Pat said, turn them over, so the outside is against the shaft. Personally, I would go with a smaller diameter thread, like an upholstery thread, or a rayon thread, and soak it in super glue, and when dry lightly sand them, smooth, with a 150-200 grit wet/dry sand paper. Just my own little preference. Very nice though.
I like them. The two fletch, like it was said, will fly as well as a three fletch, and is much easier to to do!
There fore, you can do a bunch of shafts, in the evening, and go to work the next day, and come home clean up, eat dinner, and fletch them that evening!
Yep, I like em!
