tw, seen yer arras b4, they're sweeties!
i use water based aniline dye to stain some of the shafts - it comes in powder form and i mix to the depth of color i prefer.
dye goes on bare wood first, using masking tape to separate the uncolored shaft wood. after drying, it gets 0000 steel wooled, cleaned with a paper towel, wiped with minwax gloss wipe-on polyu. progress through 3 or 4 wipes of clear w/0000 wooling between coats. for a dull finish, wool the last coat.
cresting is done exclusively with chisel tip sharpies and a pentel silver pen. they dry up pretty hard and are left as is, no clear overcoat. i don't like to spend a lotta time on finishing and it takes only 1.5 days for me to complete 2 to 3 dozen shafts, ready for fletching and pointing up.
make up some woodies, kill some kritters with 'em, it's a good thing! :D
