@Sarah-VanDam Thanks! We will be printing the images onto vellum paper.
(In case you aren’t familiar with it, vellum is a semi-transparent paper with a very soft diffused look. It looks similar to tracing paper, except vellum is much thicker & sturdier. You may have seen it used in graduation or wedding announcements. I think it’s traditionally / originally made from goat skin, but I’m sure most isn’t anymore.)
I was planning to have it in a silhouette, but I was worried that the shape of the shepherds would be difficult with their head coverings. But now I’m concerned that the images won’t match as much.
