If you're trying to get a fairy island, I suggest getting the recipes for almost everything mushroom. Like a mush lamp, mush parasol, a mush low stool, a mush table, and a mush log. I know that's not all, but that's mostly what you should use. I usually buy some of my recipes in Nookazon, but you can just get some recipes from balloons, messages in a bottle, or from villagers. Hope this helped.
