Are your neighbours getting to see a little more of your personal life than you would like? Curtains can be great for privacy but can be expensive and often don't let in natural light. A number of options are available to create a frosted glass look, including stick-on films and having the windows etched. Films can be complicated to apply and often end up looking messy and unprofessional. Etching is permanent and expensive. One of the easiest and definitely cheapest methods is painting your windows with a solution of beer and epsom salt. The method is usually used by preschoolers to paint holiday scenes on windows, but with a few tweaks, it works equally well to create privacy.
Clean your windows with a solution of equal parts water and vinegar.
Pour the beer into a 1 qt. container. Dissolve the epsom salt in the beer, and let it sit for 30 minutes. The beer should get extremely foamy.
Dip your paintbrush in the solution, and paint the window using a circular motion. Cover every inch of the surface. Allow it to dry completely. Crystals will form on the glass.
Experiment with different looks by dipping a washcloth or facial tissue in the solution and swirling onto the window in a similar circular motion. While the solution is still wet, blot with a tissue to remove some of the excess. This method will create smaller crystals. You can also experiment with stencils to add letters and shapes.
Remove the frosting from your glass by simply wiping it off with a water and a washcloth.
If you don't love the look of frosted glass but desperately need some privacy, create a stained glass look using a kit from a craft store. Kits come with all of the materials you need to create a unique stained glass window to shield you from your nosy neighbours.
