I have learned all crafting skill in 50, but on two different character. Blacksmithing \ Clothing \ Woodworking on one, and Alchemy \ Enchanting \ Provisioning on other.
And it was OK till I found that some furniture crafting recipes demanded three different professions!
So now there is a question:
1) What maximum requirements furniture crafting have? How often there is such requirements?
2) What worthwhile to lvlup for furniture: Blacksmithing\Clothing\Woodworking or Alchemy\Enchanting\Provisioning
