The challenge is a Thank You Card and there are quite a few people who deserve one of these!
Something I love about Papertrey stamps is that lots of them co-ordinate with each other. Here I've used stamps from the new Everyday Button Bits with some from the Paper Tray set issued in February 2007 which I bought second hand. I don't think you can tell they weren't made for each other!
Looking at the card again I feel its a bit "wishy-washy" - I could have used brighter ink for the flowers or even stamped them in different colours. I'll try that another time.
