Whoohoo! Thank the deities folks have gotten past that \"gun\" thing...*shudder*
Right, arrows;
The way you\'ve described is horribly complex, and perhaps a bit too intense for just a mere bow and arrows. I think a fletcher should have access to most of the items for making a bow; they can make the arrowheads out of stone or metal without needing to be smiths, and it should be something only fletchers can do. They can harvest oaken staffs and use a tool to make the bow itself. The strings wouldn\'t be made out of yarn, but probably sinew. The shafts also would be shaped in a fletching kit or something similar (I\'m drawing of Another-Game-That-Shall-Not-Be-Named, here). This would cut down with a lot of running round and allow the fletcher to actually be able to do something other than just stick bits together to make up a whole.
Combinations and pricing is up to the crafter, and as I\'ve proposed in my crafting techniques thread, may even be a special \"recipe\" per fletcher. Perhaps a Ynnwn fletcher has a special bow and arrow recipe that will not harm the race when it\'s touched (as they have aversion to certain precious metals). Indeed, race-specific bows may be worth having (the name eludes me for the water-dwelling race, but a speargun-like crossbow may suit them better underwater). That sort of thing.
Just my two bits.
