It takes some time to raise enough money and levels to make a series of major changes to your farm in Stardew Valley. And when you reach enough money and levels, you can’t easily or completely customize your farm. With the newly released map mode, you can edit and change the map and locations entirely in your own way.
Mod maker Aedenthorn’s ‘Map Editor’ mode for Stardew Valley, as it explains on its page: “Easily edits an in-game map by copying and pasting any tile to another location on the map.”
Turn on edit mode by pressing the key you assigned (F10 by default), select an existing tile on the game’s map. Then press copy, go to the tile you ‘selected’ and paste it there.
