Actually, bows aren't included under weapons in crafting. Bows are it's own little craft. You can enchant them with the feat, but can't make them with Weaponsmith, for example.<br/><br/>I would disagree with the description in the Pathfinder Create Wondrous Items feat. You have to have a weapon or armor to create or craft those items, it only makes sense that you cannot simply cause a backpack to magically appear out of nothing when the other feats all require an actual item. Admittedly, crafting jewelry is relatively difficult and expensive, but it's more, in my eyes, a facet of the ability. There has to be a base to place the enchantment on. Some of the items, Handy Haversacks, for example, actually have spell requirements tht specify an item be created. Others don't, but I really don't see it as being balanced if all you have to do is cast a spell and throw out some gold and "poof" a pair of boots appear... or even larger, more expensive items such as figurines and such.<br/><br/>You can always buy the item to be enchanted, no one says that you have to craft it. It's just cheaper to do so and when you're talking about relatively low cost items such as backpacks, boots, cloaks and so on, you're not going to be saving much... but I will rule that there must be a base to take the spell. If you want to make Boots of Elvin Kind, you'll have to have a pair of boots. If you want Bracers of Defense, you'll have to get some bracers... and so on. A necklace of fireballs? You'll need a necklace of at least glass beads.
