I used So Saffron, Crushed Curry and Crumb Cake to sponge the background over the trees which were stamped in black. It came out a bit darker than I had intended though. I mounted it onto black and then onto a white card blank.
Whisper White, Basic Black
Inks: as above
Stamp Set: Lovely as a Tree
Edited: Just added my link to LIM and see that there are at least two other similar cards! Oh well - great minds etc!
