I really can't see how you can make gold with tailoring in MoP, Blizz should of added a new bag even if it was the same size as an embersilk bag so we can actually make something with the cloth we collect.
Royal satchel with be very expensive due to how many spirit of harmonies it will take to make it unless you wait 12 days and just use the cooldown so due to this the cost will be high and it'll have a limited market. The PVP gear is worthless as it costs next to nothing to make, the epic robe etc we could make has a lower ilvl than the raid finder gear so it will also be worthless, any ideas?! I'm tempted to drop it and go with inscription alongside my other profession - enchanting which i'm hoping will be a viable gold maker!
