For the other card I actually pulled out another distress crayon that came with one of the summer kits last year to create a bit of an ombre effect. To do this I colored on the card with the yellow and pink distress crayons, then used a watercolor brush to blend it together. Then I added some puffy stickers. That's it!
For my last 2 cards I used the heart embellishments from the kit along with some other elements from the kit. I think the card with the Elle's Studio strips is my favorite :)
