I still have some of the Stampin' UP! Simply Marbleous 6 x 6 dsp and saw this idea on Pinterest.  The card on the right is actually the first one I made.  I cut a 3" circle from the gray piece of dsp.  The sample I saw had blended the coordinating ink around the area before adding the circle to the card mat.  The samples I saw had all used black silhouette die cuts to add to the circles so I pulled out several from my "collection".

After completing that card, I felt like the dsp got lost so I cut another circle and matted it with the Basic Grey card stock but didn't do any blending with the ink.  I like it much better.

I will be posting more cards using some of the other colors of this dsp and other design added to them.

Thank you for coming by today!
