Crafting is one of the fundamentals when playing Voyagers. Everything is made from crafting. To craft an item, press G and assort the items into the Crafting tab and press the crossed tools icon to craft. If you're curious on how to craft something, the recipe can be found on the page of the item (on this wiki). Be careful, however, because some crafting recipes are closely guarded secrets. This is to prevent abuse and rage quitting from players of the game.
