Next I will show trimming the feather to roughly the size and shape I want. I usually make them about 5 inches long not counting the quills used to secure the feather to the shaft. Starting about 2 1\2 inches from the outer tip of the feather, I will peel the taller side of the feather off towards the quill. If you manage to do so without tearing it, save it. You can use the part you peeled off on normal fletching jobs. Next very carefully cut half way through the quill, just below where you peeled off the feather. If you cut all the way across you've already ruined it, start over with another feather. Once you cut in half way, start to split the quill all the way towards the base of the feather. Now on the other side of the quill you should have full length vain along the quill. Starting from the outer tip of the feather, measure down about 6 1\2 inches and seperate the vain of the full length side. From here, peel this side off toward the base of the quill. This should leave you with a 2 1\2" vain on one side and a 6 1\2" vain on the other. Now clip off the quill 1" below the long vain side. Use the edge of your knife like a scraper and remove the pithy part of the quill and flatten it for 1 1\2" inches from the base end so that it will lay flat against the shaft later. The next step is, starting at the outer tip and using scissors, cut the vain next to the quill 1 1\2" towards the base. do this on both sides, so that the quill is sticking up above the vains.
