Sometimes net curtains just do not cut it, but having bare windows can make you feel naked to the neighbours. If you are inclined toward creativity and have no fear of wielding scissors, there are a few techniques you can try on a temporary basis, like frosted glass and decorative film. Don't worry; if you do not like the results, you can always go back to nets.
Homemade Frosting Solution
Perfect if you like the look of frosted windows; make your own frosty home brew by dissolving 4 heaped tbsp Epsom salts in 1 cup beer. The mixture will foam upon contact, but let it set for 30 minutes, allowing the salt crystals to dissolve partially. Dip a terry cloth or handkerchief into the solution and wipe it over the window as though you were washing it. Before it is dry, dab the window with the wet cloth. Once dried, crystals appear. If you don't like it, wash it off.
Semi-Permanent Frosting Spray
Place a piece of tracing paper against the window, and trace the size of the window. Cut along the tracers and affix back onto the window, using temporary adhesive. Chose the shape you want on your windows, and trace the design onto the paper on the window. Take it down from the window and cut out the design using scissors. If the design is complicated, use a craft knife. Affix the paper back onto the window and spray over it with frosting spray. Once the spray has dried, take the paper down to expose the design on your window. Should you not like the affect, use a razor blade or rough cloth to clean the windows.
If you want a change, but prefer it to be as easy as possible, try decorative film. Cut it to size, remove it from the backing surface and spray it and the window with a soapy solution. Place the film onto the window and manoeuvre it into place. The spray stops it from sticking immediately. Using a squeegee (a hard plastic thick item like a ruler) and squeeze all the excess bubbles and spray from the centre to the edges. Blot the excess water with a kitchen towel and give the window a couple of days to dry. If it doesn't suit your room, simply peel back a corner and carefully remove.
If you are creative, try painting a stained glass window. You can buy window paint in a frosted look, or be more adventurous and paint your windows different colours. Also available to buy are lead paints, which mimic the look of lead in your windowpane to give your artwork some structure. If you decide you want to start again, gently score the paint and pull gently to remove.
