Party This Way, Done Three Ways

Hello Again! Today, being Saturday, means I have the day off, and new challenges have been released at some of my favourite blogs!
The first challenge, which I am entering all three cards in to is the Just Add Ink - Just Add Birthdays Challenge.
The other challenges, I am only entering the first two cards into. The Clean & Simple sketch challenge, and the Stamping 411 One Layer Cards challenge.
In all three cards, I used the Party This Way stamp set, which is one I ummed and ahhhed over before taking the leap and purchasing... I wasn't sure if I would use it, but looking at this post, and a few of my previous posts, suggests I do actually use it, and love it!
So, on to the cards....
