It's not necessarily useless. You just have to be a little creative with your selection. Profession [tailor] lets you make clothing [cloaks, tunics, caps, leggings, etc]; craft [leatherwork] let's you make boots, gloves, belts, necklaces [leather thongs], leather vambraces, leather cloaks, leather hats, pretty much any garment made of leather; profession [scribe] lets you make tomes/manuals of +5 [at level 17, anyway] at half price [a sweet deal alone]; if you have a cool DM, you could use craft [armor], craft [leatherwork], and profession [tailor] to create virtually any slotted wondrous item [except for lenses]. Why? Custom magic item creation basically just states what slot something has to occupy, not what form it has to take. You could make an armored gorget that functions as a Gorget of Natural Armor, a pair of armored boots that function as boots of speed, armored vambraces that function as bracers of greater archery, pauldrons that function as a cloak of resistance; the same could be said for items of clothing or pieces of leatherwork [leatherwork is probably the best bet, as it can be used to make bracelets, necklaces, virtually every form of garment, belts, etc].
Obviously, it's a feat that requires some DM fiat, and you probably won't be able to make *every* type of wondrous or magic item, but it could be feasible to create a mundane class christmas tree wizard.
