This is done with silver heat embossing. The stamps are from the sets Lovely as a Tree, Star of Light and Christmas Pines for the Sentiment. The card stock is Island Indigo and Whisper White thick for the card base. I also matted with silver foil paper. This is going to one of my artsy friends.
This is my favourite so far. Only one thing has retired: the Framelits used to mount the sentiment. Everything else is still available. The stamps used were from the Reason for the Season set for the poinsettias and the sentiment and Lovely as a Tree for inside the window. I used the Hearth and Home thinlits to cut the window frame. The inks used were basic gray for the outlines of the poinsettias and tree and Emerald Envy for the sentiment. I coloured it all with Stampin Write markers in Emerald Envy, Cherry Cobbler, Real Red and Crushed Curry for the poinsettias and inside the window: Garden Green, Real Red, Daffodil Delight, Pumpkin Pie, Tangerine Tango and Cajun Craze. I used the Brick Wall TIEF on the Cajun Craze card stock and the other card stocks were whisper white and real red.
