A Christmas Card

Here are some Christmas Cards I've made using the Stampin Up 'Contempo Christmas' set.  The stamps have a matching punch which I used to cut them out. I wanted to come up with something relatively easy so that I can sit down and do some mass production for my work colleagues.  I've tried two colours, Real Red and Marina Mist and I think they both work well.

I'd like to enter these into the following challenges:
Paper Crafting Journey - Anything Goes
Fun with Shapes & More - Maritim / blue-white and/or red-white
Alphabet Challenge - 2W, 1E, JFF - Week 2, O … only one colour + white
