Seize the Birthday has become one of my favorite challenges; possibly because at least half the cards I make each year are birthday cards. Any birthday card is allowed for all of the challenges, but there is also a "topping" challenge each time. The current topping is "stamping only." Theses cards almost meet that criteria. Both cards do use a Stitched Circle die from Simon Says, and a few rhinestones, but it's probably as close as I get to a stamping only card.
Both cards use Simon Says gray cardstocks and Simon Says "Bohemian Lace" stamp set. The sentiment for the card on the right is from Papertrey Ink's "Good Times" stamp set, and the one on the left has a sentiment white embossed on a thin black strip from Mama Elephant's "Occasional Labels." Here's a closer look:
I've put creating a stamping only birthday card on my "to do" list. The challenge is open until January 29th, so it just might happen!
