I usually do my own fletchings. Over the years I've done spliced fletching, dip and crest, and self nocks, footed arrows. If you need to hide out from the world for a while its a great way to pass time. lol
I used to be big into building my own wood arrows and even made the shafts and have picked up bamboo from ebay but lately there has been to many other time consuming hobbies and interests so now I just get a dozen trad gold tip shafts from amazon and go from there.
Here's a couple of items from back then...
Dipped and crested:
spliced fletching
rose wood self-nocks on bamboo
