Sack

An Empty Sand Bag can be filled with dirt to create a [Dirt Bag[Dirt Bag]]. A dirt bag is used to spread dirt over a tile, allowing the tile to be [Trowel[tilled]] for [Farming[farming]]. A sand bag can be filled by right-clicking a patch of grass with both the Empty Sand Bag and a [Spade[Spade]] in the player's inventory, and using the action "Take Dirt > Empty Sand Bag".
