For Bitten by the Bug2 challenge, hearts, I used the Sweethearts and Holidays Through the Year Iron-On cartridges and free SVGs.
The hearts on my card are found on the tiny flowers from Sweetheart's Three Heart Flowers -- as are the wings on the love birds (a free image of the day from Miss Kate Cuttables). Such dainty images - I cut them on the intricate card stock setting and they cut beautifully! And the tiny stems glued on to the card base hold nice too. The silhouette couple was a free image that I saved last year. I don't remember where I got it though. The girl was supposed to be holding a flower - but that was too thin to save, although it did cut.
