2. Post lights on deck railings can add character and more usable and safer at night! Putting them on a dimmer switch would give even more flexibility to every occasion. Possibly running those string lights under the top board of deck railing for ambiance.
3. Make your porch a livable space. Add homey touches such as a ceiling fan, comfy furniture with pillows and blankets, paint the floor, speakers for music, pictures, lights.
4. Hang a mirror on a wall or fence that will give the illusion of a window into another yard or room

6. Elegant netting hung around a bench or daybed creates romance, privacy and bug free area!
