Make a design or pattern on an empty tin can using a pencil. For example, you can make a heart or even just lines. Pour water into the can and freeze.
After the water is frozen, take a nail and hammer to perforate holes following the outline of the design. Be sure not to cut out an entire section. For example, if making a heart design, hammer in a hole every other centimeter or so to make perforations resembling a heart.
Hammer in holes on the opposite sides of the top portion of the can. The holes on top are optional for hanging purposes.
Place a small candle into the can and light it. When lit at night, the candle will illuminate through the holes, displaying the design. The small tin lanterns can be hung around the trees or lined on a pathway to add an enchanted and homey element to your garden.
