At the very beginning of the game, there's a great technique to earn a profit. Level up Edwards first, doing so by making the Cork Bow. Once your party reunites after saving Aya, head back to Nolaan. When you can make the Smile Charm, go to town and buy Sheep Skins, as many as you can. It takes two Sheep Skins to make a Smile Charm, and while the materials cost you 240, they will earn you 1,500 when sold!

Later in the game, when you can go to Port Zala, you can buy Iron and Granite from Faina, allowing you to make the Horseshoe Charm. These items sell for 2,600! Both of these techniques are quick and easy, so give 'em a try!
