Using a craft knife, scissors or a circle-cutter, carefully cut out the images, not forgetting to include the square tab at the top.

If you want to add colour to your image, do so on the printed side, using the inks or dyes of your choice.

Glitter, Stickles or white gel pen embellishment should be done on the opposite side and left to thoroughly dry.
Remove the top from the bauble. (The easiest way is to simply pull it straight up).

Holding the cut image with the tab at the top, loosely roll the acetate into a tube from the side, and slide it into the bauble. It will spring into position with the tab sitting in the neck of the bauble.

Swizzle the tab so that the edges of your acetate line up with the faint ridge where the two halves of the bauble were joined during manufacture.

Now add a little faux snow, glitter, stars, and the like, into the bottom of the bauble. They look great just like this, or you can let your imagination run wild with tinsel, lametta or feathers behind the image.

Replace the top, ensuring the prongs sit behind the tab.
