You can have 10 crafting skills at 0-20, then 6 at 20-40, then 3 at 40-60, then 1 at 60-80. Each boundary requires training to cross and some mats.
Heffner trainers are a lot more forgiving, by the way. They will move you across the 20 and 40 lines for free, just by asking. I suggest going there. For 60 line, Dalanis has the trainers for all crafts.
Only exception is planting. Planting does not count toward your 10,6,3,1 limits, and master (L60) trainer is in Varanas, not Dalanis.

Oh, and people who have more than 3 classes are clinically insane.
