@rundocuri- You certainly don't have to spend a lot of money to have a nice outdoor sitting area. There are several easy and inexpensive ways that you can dress up basic, plastic outdoor furniture so you can accomplish your goals.
The easiest way to make plastic furniture look nicer is to add covers or cushions to it. These items are available in most outdoor living sections of retail and home improvement stores, and they come in a wide variety of colors and patterns. A good tip to follow when selecting furniture covers and cushions is to look for those made of weather-resistant materials so they last for many seasons of exposure to the elements.
Another easy and inexpensive way to enhance plastic furniture is to paint it. This type of furniture is available in limited colors, but spray paint comes in almost every color imaginable. You can even paint your outdoor plastic furniture to match the exterior of your home for an added touch of style. Just be sure that you choose paint that is formulated to bond onto plastic so it will last and won't chip.
