Karen ~ Good luck!
I once spent a week making ice luminaries to line our driveway for our annual Christmas party. Bobcat laughed at me the whole time.
They looked great. This isn't our photo, but they turned out something like this:

The night before the party, I took them out of our deep freeze and set them out on the deck. Figured they'd be safe, after all it was December in Alaska, right?
Around midnight, a Chinook (warm winter wind) came down from the mountains. Bobcat felt bad about laughing at me when we awoke to find them melted down to nothing.
