This method is possibly one of the most effortless money-making strategy in the game. Basically, to sum it up, all a player has to do is pick the flaxes from the field, same
procedure as picking grain to make flour. Flaxes are averagely worth 75-100gps each.
There is only one flax field, and that is located next to the Beehives field south of Seers Village. Simply click on one of the respawn points to gather up the flaxes until you have a full inventory, and then deposit them at the closest bank in Seers Village. A person can easily make 30k per hour with this method.

In addition, you can take this step a little further by turning the flaxes into bow
strings, which have a little more quality over flaxes. However, you may not be able to
make as much money as just selling the flaxes raw, but you’ll able to gain crafting
experience in the process.

To turn the flaxes into bow strings (requires a crafting level of 10), head on over to
the shack with the spinning wheel in the second floor located two houses down from the
west side of the bank. Click on the spinning wheel in order to spin the flaxes into bow
strings, then deposit them, and repeat the same procedure as often times as you want.
