I saw a card in the gallery recently that had 3 ornaments hanging. It was done with build-a-brads as the ornaments with hand-drawn lines for the hangers. Could this be the one you're talking about?
If not, maybe you saw something done with the set Hung up on the Holidays (that might not be exactly the right name :confused: ). It's a set with individual ornaments that you place where you want. You could do a gallery search for this set to see if it's the one you're wanting.
Hope you find the stamp(s) you're looking for!
