I won't be saving these cookies though. They would get stale and they can't sing and also they don't look anything like the Von Trapp Family. But they are really easy to make. And fun.
And... I actually made a low-quality video to prove it to you.
But if you aren't into videos... I also made this. Use 15 count icing for everything except the ties for the cans. Let it dry between each step. Repeat hundreds of times.
