Never been an easier (6 piece) stained glass santa clause ornament pattern. You can make dozens of these up in an hour.

IF you want to make window clings, just cut a stiff plastic backing the outline, for each ornament, and paint with gallery glass or other stained glass paint.  Leave the window cling attached to the plastic and punch a hole in the top (instead of the metal loop used for stained glass) and tie in a ribbon.
