Here's a snowglobe I made for my neice for Christmas. She was up north when I had a little fun figuring these out and she told me she wanted one for Christmas....my first one didn't turn out too good. I had some trouble getting the acetate cut in a circle that would fit in the glass ornament....and being up north, I had limited supplies, so I got it figured out when I got home. She's going to love it!
