Crafting is a main mechanic of Alchemy Garden.
What do you need
In order to craft tools and furniture, you'll need a workbench. It can be bought in Pop the Traveler's store, in the town center. It can only be placed indoors.
How to use the Workbench
Interact by pressing the E key. A list of craftable items will appear on the left. Select one to check what components are required for crafting. If these components are in your inventory, you can craft the item. If not... mostly of them can be found taking a walk through the map, or visit Pop the Traveller's Shop.
