Here are the arrows I'm making for my latest set, Apache style. The arrows are not reproductions but are very close. The main differences are the spiral fletching (all the Apache arrows I've seen have straight fletching), the lack of red paint under the fletchings and the type of feathers used.
The first thing I do is select the phrag.
I try to get pieces that are 1/2" at the base and 40+ inches long.
I process the phrag as soon as I get it, whether it is green or dry.
If it's green, I dry it in a warm sunny place for two weeks (after processing).
The first step in processing is to remove the leaves and trim the leaf stems off the nodes.
I've seen this done to most of the Apache arrows I've seen in illustrations and exhibits.
Then I cut and bundle them together according to how the nodes match - tip and nock.
I noticed that on many Apache arrows the nodes at the tip are random, but the nock is always cut just below a node.
