You need Thread to build fishing rods, and ropes to repair the docks, among other things. This guide on Where To Find Thread In Summer In Mara will tell you how you can unlock the Thread recipe so you can make your own thread to complete other recipes that require this ingredient.
If you’re reading this guide there is a good chance that you’re still on the starting island looking for thread so you can make rope to repair the docks. Unfortunately, there is not enough thread on the island to complete this task. You can find some, such as one hidden in the box on the broken boat at the beach, but not enough to do the repairs. Simply board the boat anyway and head to the mainland, Qalis.
Where To Find Thread In Summer In MaraWhen you reach the mainland you have a Koa quest to meet the lady at the lighthouse. Head to the lighthouse and speak with the lady. You learn she’s not keen on bad manners. Return to the dock and speak with Noho there. He will tell you another wonderful story before asking for an item in exchange for more information. This is where you learn the Thread recipe. You are also given some Cotton seeds. You need to return to your island and plant the Cotton seeds.
Once the Cotton has grown enough to harvest you must harvest it and then use the Workbench at the house to make the thread. You need two pieces of thread to complete Noho’s quest. You now have access to the thread recipe for the rest of the game.
