Attention Jewelcrafters: Don't miss out!

I've heard a lot of people in Trade, my guild, and a few people elsewhere complaining that Jewelcrafting isn't profitable right now. I ask them what they're selling and more often than not they aren't selling 450 jewelry; in fact they don't even know how to make the 450 jewelry! That's a pretty big problem for the gold-making jewelcrafter and it's a problem we need to fix right now!
