I had the vision and my super stud executed it, while I was getting ready to prepare a "breakfast for dinner" feast for our friends. All that is needed is two distressed windows, some fishing line, a few small nails, and sparkly snowflake ornaments in various sizes (we got ours 4 for $1 at Target). Hammer the nails into the top of the window frame, every few inches (on the side that will be against the wall). Tie strings of fishing line to each snowflake, then hang at varied lengths on the nails. Finish by hanging windows on the wall. Let it snow, let it snow, let it snow.
Unfortunately, we are renting so we can't paint the walls. But just imagine how amazing the snowflakes would look on a wall painted something other than off-white: charcoal, teal, espresso, red...I could go on and on. When I find time, I will definitely be painting the frames a better color to pop off of the white walls, because white with white on white = no bueno.
