DIY Mercury glass mason jars. Looking glass spray paint, equal parts vinegar/water spray bottle. Spray with water mix then add light coat of spray paint. Allow to dry. Use a paper towel to wipe away bubbled areas for completed look.
Spray wine bottles with water. While still wet, spray with Krylon "Looking Glass" spray paint. The water will keep the paint from adhering completely and give the "splotchy" look. Then, you can etch the words! Hoping to make something like this soon :)
