I cannot say this enough: Make a Spread Sheet.
In the Spread sheet put down what Tier Crafting Stations are required to make what type of Materials.
“I have a list of Each Town broken down with Each Crafting Station.
My Server’s Loom Tier was not above 3 in any Town at one point. I Used this to my advantage and Sold all my Silk for a Stupid Amount of Gold.”
This is very easily done with Each type of Gathering Material. Please try thinking outside the box and you too can have a stupendous amount of gold.
Buy Cheap Tanning and Convert them into Solvents or Sand paper or Flux and then turn around and sell them. There are ways out there to make Gold, You just have to look for it. Play the market.
