The FREE designer paper is Delicate Dots. The colors are So Saffron, Certainly Celery, and Bashful Blue.
The stamp set was not free but still wonderful. It is Branch Out (page 100 in the 2009 SU catalog). I love that the tree and the green 'leaves' are separate. And so is the little bird stamp. I love to build layers like that for my image, without having to use markers.
