-Scissors or X-acto blade
-Lead pencil, metallic marker, or other tracing tool that'll show on a black surface
-Black (or colored) contact paper (recommend for simplicity)
-Clear contact paper
-Paint, permanent markers, or paint pens.
(*pick up contact paper from your local dollar store to make this project super inexpensive!)
1. Draw or trace an image onto your contact paper and cut it out. (this may take some patience if you picked a detailed image)
2. If using clear contact paper, paint/color it appropriately.
3. Hang on the window -it's that simple!
I ran out of black contact paper for the Fellowship of the Ring cling, so created that one for illustrative purposes. As you can see, one layer of marker isn't dark enough; if I had planned on making it a more permanent decoration, I would have definitely added more layers of color to eliminate the marker lines. I also cut flush around half of the decal and left a small border of plain contact paper on the other half for you guys to see the difference in that manner too.
I chose to make silhouettes for a subtle look, but feel free to make an entire colored scene if you wish. What's great about the contact paper is that it won't peel/fall off the window like normal store bought window clings, plus it won't leave a residue when you decide to remove it. Further, the contact paper route is much cheaper than the vinyl option and looks just as cool! Make your images as small or large as you choose. Store them on wax paper between uses (switching up the decor for a holiday?) and reuse more than once.
