Fletching.
I soaked the feathers while I was painting the shaft.
After applying the pitch, and letting it cool, the arrow is ready for the fletching.
Without the pitch, water from the feathers would make the paint run.
The rear ends of the feathers are trimmed back about 1/2".
Then fastened with a wrapping of deer sinew & fish glue.
Then folded forward.
The front of the feathers are wrapped, fletching pulled tight, and finished off with a little more sinew.
Then the feathers are smoothed back into shape using a little heat from the fire and more water.
The stiffer the feather, the longer this takes. Soft feathers are shaped easily....that's why I usually use tail feathers.
Then I burn the feathers to shape with a hot stick.
I keep the end glowing hot by blowing on it....if there is no wind.
The End.
