Cut greens from the yard (I used Boxwood) and cranberries to fill the sides. Cranberries float, so place some in the bottom first and then add green on top. Add a few additional cranberries on the sides. When you fill the container with water the cranberries will rise to the top.When it’s frozen, remove from the freezer. Lift tape and add hot water into the center of the bottle. As the ice melts a little, pull out center bottle. This gets a little tricky as the plastic bottles have larger bottoms than the sides. You have to work it! Run hot water over the outside of the bottle to loosen the large bottle. I had great difficulty pulling the ice lantern out of the 2 liter bottle due to the larger bottom.
