Before I stamped the tree, I lined up the alcohol ink colored piece and lightly traced the scallop circle onto the cream cardstock. That way I could be sure the tree was mostly centered in the circle and nothing would be cut off when I attached the alcohol ink colored piece.
I stamped it with Stazon in brown (I think) but it might have been Memento Rich Coco. Either way the pad needs some reinker. I then water colored the ground and leaves with Distress Inks (for list of colors see the bottom of this post). I also inked the edge where it would show through the circle because it was just too much cream cardstock showing.
