Incorporate color with textiles
Add a personal fair to your deck or patio by incorporating some outdoor textiles that add style and color. Once you pick your color scheme, choose a range of patterns for your pillows, rugs and other textiles. Make sure you choose fabric that is resistant to sun, can dry quickly and is easy to clean.

Create an oasis with plants
Cultivate your oasis with lush plants. Layering plants is a great way to add texture and liven up your space. Use greenery as a centerpiece for an outdoor table, and arrange plants near your seating area. Use plants with tall stems and full leaves as a natural privacy screen.

Use outdoor lighting
Make the most of your backyard even after the sun goes down. Get creative with lights that illuminate walkways and paths, and also provide a good ambient glow. For hangout areas, use hanging and solar powered lights.

Make sure you have some shade
Create some spots in your yard where you have a respite from the summer sun and heat. Arbors, canopies, and even well situated plants can all provide shade from the summer sun.
Get a fire pit
There's nothing like relaxing around a fire pit when the sun goes down. Fire pits are a great way to draw people together, and extend the usefulness of an outdoor living area into cooler weather.
