Vintage Christmas card ... reminds me of my German Grandmother. Yes, @Christiane Boles and @Ann Woods Hawks?
Use bottles, soda bottles, beer bottles, or wine bottles. Cover a part of a bottle in red paper. Spray paint everything else white and cover the red with stripes of white, and turn it into letters.
This is a great way to bring the outdoors in. Attach the snowflakes onto clear filimant and suspend from the ceiling with Master Command mini christmas light hooks. The more strands the greater the impact in a space. This is a great idea for kid playrooms, the dining room, even the front entryway.
