Yonder: The Cloud Catcher Chronicles (EP)

This achievement is best done later in the game when you have acquired some materials. I would also recommend gathering berries and milk from your farms for the purpose of trading.

Quest boards can be found in any major town. Walk up to one and check what someone is requesting. Most of the time it will be something like craft a firework or some hedges or catch some rare and time consuming fish. Decline those. Keep refreshing and I promise you'll find easier ones. I got one for 40 sticks, one for some mushrooms and meat, one for two haberdasheries, one for some iron ore, etc.

You can buy a good amount of materials from shop owners in exchange for your farm goods. If you leave the store and talk to them again all the items are replenished. And im not sure if it's a glitch but I found the more of one item you buy the cheaper it becomes. So if you need a large amount of something just keep spamming the same shop and it'll become cheaper every purchase.

The most annoying part of the quest is walking the item over to the person that asked for it. I did it in Wimblewick, the top left town that has the boat to the desert. If you cycle through the quests and find an easy one make sure it doesn't say deliver to Interlade Troll. You'll need to build 2 bridges to get over there and it's quite a walk.
