I love this paper from Echo Park (should've bought more...) and I wanted the background to 'show through' the jar. I used the Unity Stamp September 2013 Kit of the Month. So I paper pieced the jar and positioned it over the background so that the hot air balloons line up. I also stamped on some clear transparency and glued that over the jar with a cut-out heart (from the same set) behind it.

One of these is for the birthday of a little girl at church (I wanted something fun and 'heart-y') and decided to make two so I can keep one for another occasion!
