congrats on 99 fletching
start working on combat perhaps? get your slayer up while you train combat.
or you could superheat gold bars with gauntlets which would raise your magic and smithing levels (about 75-80k xp per hour in both skills) and then raise your crafting by making gold bracelets with the gold bars. you will break even and probably even make some gp because gold bracelets sell easily on the GE due to people alching them
so you could get 99 magic, smithing, and crafting in about 2 months if you work on it. and those are all pretty sweet capes
