I love the dimensionality of this card. You could easily do it in darker blues to show night time if you wanted to. You could also dot coloured Stickles on the tree to represent lights or tinsel as well.
heat embossed the Joyful Wishes poinsettia's with Silver EP on the Vellum card stock. Then she sponged Classic ink underneath and cut the flowers out by hand. I believe she used Pear Pizzazz and Bermuda Bay or Pool Party ink.
