Buckeye, here is one option with smaller feathers. I believe it is called a tangential 3 fletch...
this is a primitive arrow James Parker gave me a few years ago with this type of fletching.
pat-thanks for posting these. i have lots of smaller feathers and tho i use em on other projects too, i keep thinking there's gotta be some way to use em for fletching.
after thumbing thru the encyclopedia of native amer bows arrows and quivers(both vols) a zillion times by now(they are beginning to get worn and ive only had em a cupla months)
they obviously used whatever feathers they had on hand. yes, of course, many are "traditional' fletches but they used all sorts of "other" feathers too.
thanks!!
