If you want to make your own wishing well, build a large box or repurpose a wooden container to make the base. Once you have the base of your well, build a small, peaked roof, with a secure frame that attaches to the sides of the well. Generally, you don’t want the roof to extend past the sides of the well.

Hang a bucket from a rod placed about halfway between the well and the roof to make it look like a real well! For tips on adding water to your well, read on!
