They do allow for a mat layer but I've kept my card one layer. I've used some stamps from a set I got from Clear Impressions called Rural Springtime. There are some lovely stamps on it and I chose to use three from the set.
I first used some Tim Holtz Distress Inks in Bundled Sage and Tattered Rose to make the background. I used Tim's new, to me, Stamping Platform to add my stamps. I found the platform great for this type of stamping where I was positioning a few stamps to make sure they ink correctly and in the right place.
I used some of SU Melon Mambo for the sentiment and a touch of Wink of Stella on the trees just to make them sparkle and give the card a bit of interest.
