First make a 4x4 square out of Wood, leaving the centre four blocks open.Step 2
Place a Fence post in each corner and then on top another identical square of Wooden Planks.
Fill the gap in the Wooden Planks with Wooden Slabs to make another layer, adding to the detail.
Now, use the Water Buckets on opposite corners of the Water store to make a 2x2 unlimited water source, so you will never have to go looking for lakes again.
