I used Gesso, mica sprays and acrylic paints to form a background on each card. However, once I attached the chosen pictures, I didn't like the cards so I started over again.
I cleaned up the backgrounds, adding a few hearts here and there.
I chose my pictures from my stash, I'm sorry I can't say from where they originated, and then coated them with clear lacquer.
Once the lacquer was dry I fussy cut the images, leaving the tops heart shaped.
I added them to the backgrounds and then trimmed up the cards.
I added an extra card for this swap as a 'Thank you for Hosting' card.
Using the same technique as before I fussy cut the Giraffe and then edged the image with brown ink. I added it to the yellow sparkle background. I hope that it is acceptable.
UPDATE:
I received the following cards.
Sparkle and decoupage.
