We will be making snow globes as part of our Shepherds and Angels rotation this year, getting the kids to dress up as either angels or shepherds and then taking photos of them posing in front of a dark backdrop (blue or black sheet) with some fairy lights as the stars at the top. They will be dressed in the nativity costumes we already have. The photos will be laminated and then placed into jars with grated PVC pipe (for the snow) and a bit of glycerin so the snow falls gently when the jar is shaken. There are instructions on the internet if you want to see photos or step by step, just google "DIY photo snow globe" and you will have heaps to choose from.  Here is one example.
