MMORPG.com Ultima Online expert V D has provided us with this Bowcraft Skill Guide for the classic MMO.
Bowcraft and Fletching is the skill that is useful to know if you are going to be an Archer. They go hand in hand because this skill is what you need to know in order to make bolts, arrows, bows, crossbows, and heavy crossbows. Ideally you should put this skill on your crafter character.
It’s very easy to reach GM with this skill, it just takes a while. Make sure you have tons of boards (100k to GM) and have a lot of empty bags available and at least 20 fletching tools because they do break often.
Be sure to have an empty bag or container in your backpack that you can put as many boards as you can carry. When you double-click your fletching tool and select the item you want to make it will automatically be created inside that bag. This is useful for when you get too heavy and just want to empty out you backpack, because you can throw full bag away:
