These have been my bread and butter for early level gil making. I strongly recommend leveling THF to 20 and farming these while camping Stray Mary in Konschtat Highlands F-6/7/8/9 & G-6/7/8/9. I like to bring stacks of wind crystals to synth Sheep Wool (level 4 Leatherworking wind crystal + 2 sheepskins), synth materials for Sheep Leather takes up too much inventory space especially if you haven't completed any of the Gobbie Bag quests. Stacks of Sheep Wool sell in Windurst auction house for about 7k per stack. Grain Seeds sell for 8-12k per stack in most auction houses.
