This card took a lot of masking.  You stamp the image on printer paper (thin) and then cut out, I made four of them.  You stamp the image so they don't touch each other on the paper.  Then you put your mask over each one and stamp next to it so you are overlapping the images.  You will need more than one mask when you get them closer to each other.  I used glossy white paper, but you don't need to.  I just like that it is shiny when you are holding card.  I used Touch of Nature for this card, and It's your Birthday.  I also used our silver cording, and the Crop a Dile to emboss the circles. 
I can teach you this technique in person, just let me know when you want to do it!
