I made this heart shaped ice for my Dad for Valentine's Day. The funny thing was that Mother Nature had other ideas and the temperature rose to 50 degrees on Monday! So, I had to wait until the temperature dropped again. Luckily, this happened the next day.
The next day is was frozen solid. I peeled off the foil and transported it to its destination.
This would be a great project for decorating an outdoor Christmas tree. I'd make smaller shapes and make a hole to string them with. Or maybe even making an ice wreath.
