Very nice!
Like anything good, this stuff takes time. I have been tinkering with wood arrows as of late myself and for practice I have just been sealing them up with spar urethane and steel wool between coats, fletch and go.
This weekend I am doing up half a dozen I want to hunt with this fall. I make my own salt water plugs from kits so I have a lot of experience with rattle cans. Hands down, Rustoleum enamel spray cans are the top of the heap for the DIY hobbyist. I don't get into airbrushing, etc but Rustoleum covers evenly, and dries hard and is durable. Also, stay away from that cheap painters tape. Use 3M. Its worlds above the store brand stuff that tears and allows seeping of your paint lines.
When these are done, I will post some pics. They will be a plain white cap and white feathers. For hunting deer I like white for tracking my shot and evaluating the blood of a hit.
