I have used some green cardstock as my base (I think its Stampin Up), white cardstock, We R Memory Keepers White Out paper and rub ons. Plus stickles(Samantha is rubbing this off on me - I am using more since we get together frequently) and blue eyelets so the person who gets the card can hand it if they like.
On another note, I am very lucky to have James at the moment he has made me a frame for my Advent Calender. So it has really been a joint effort to finish it. I will post a photo once I have finished painting it.
