First state that by becoming a tailor, you are starting down a long, long, long road. The tailor profession is considered by many to be the hardest (but most profitable) profession in the game. In other words, the light at the end of this tunnel will be very bright, but the time it takes to get there will be very long, and the amount of Mabinogi online gold that you invest, well, you probably dont want to know.
Secondly, if you are f2p (free-to-play) and plan to stay that way, dont even bother. You really dont make any money as a tailor until level 40, and its a HUGE Mabinogi money investment until then much more than what a f2p can bring in. In mean, you cant even get a tailor manual unless a p2p (pay-to-play) gets one for you – small hint there.
