Have you played with the Holiday Lounge paper yet? It's so awesomely modern and retro. I love it!
I took the tree from Sparkly & Bright and used markers (Sahara Sand, Real Red and Bermuda Bay) to ink it, then a 1-1/4" square punch to punch it out of the Whisper White card stock.
A snowflake from the set is stamped in Sahara Sand on the Sahara Sand card front, with a strip of Holiday Lounge paper adhered to the left.
