When you say make your own, you mean fletch your own and glue in the inserts like aluminum or carbon? Or do you mean going out to a river bank and collecting cane and cutting and sorting, and straighening, and then collecting your own turkey feathers and cutting the feathers, you get the picture. Or just buying some cedar dowls, sealing, etc.
