I layered the scene inside similar to a tunnel book to make it a bit more interesting then covered everything in pounds of Winter Snow Glitter Mix and a bit of dimensional snow.
To make the layers inside the ornament, four pieces of watercolor paper were cut the same width as the diorama box and twice as long. Any thick paper would work, I just chose it because all of the images are colored with watercolor pencils after they were stamped.
I began folding the paper beginning with the foreground (which is also the background, which willl hopefully make sense with the photos). That piece fits the back of the box and is folded to fit along the bottom of the box, then folded one more time for the foreground's "snow bank". For the next layer, I stamped a Christmas tree on one side, folded the paper as before, then stamped background trees on the other side. This method was continued for four layers before I trimmed around the house and all of those teensy weensy trees. The images were colored, glittered, and stacked together with adhesive foam dots in between.
All of that fit snuggly inside the diorama box. Covered it in paper, added some tiny white snowflake buttons, snippets of a silver juniper pick, and a hanger, and poof! Instant gift.
