Details of this challenge can be found on the blog of Winter Wonderland:
I particularly like this image and have used it before in greens. It has come up really well with a blue colour scheme.
Materials used for the card:
The Sherlocks Home - Mattie Elf
Various scrapbook papers
White grosgrain ribbon
I am not sure if the digital stamp is still available as Mattie now appears on the Folded Paper & Printed Pixels blog. I had a quick look to see if the above image was in the shop but didn't notice it.
