When creating the outdoor feel you can't forget string lights that can run across the backyard or the patio.  Warm Colored light are better than the pure white lights to create that welcoming and inviting look, especially on those cooler days.  These have bulbs that are lightweight, waterproof, and shatterproof, not to mention they save electricity since they're LED.  We have a few of these in the back at both Avalon and Nimbus.  At Avalon, we have this stringed along the fence line held up with good old reliable zip ties.  At Nimbus, we created a base with wine barrel planters and bolted down 4x4 posts to hold up the lights.

Walking down a pathway at night without guiding light can lead you off the path, bumping into something or maybe stepping onto a wet lawn.  Ground lights help guide the way, and these also have the warm yellow lights that help create the inviting feeling.  Put it in an area without a lot of shade cover.  We put some of these in the walkway leading up to the front door, which only gets direct sunlight for only 3 hours in the day, but they're still able to pump out light for hours.  They're quick to set up, you never have to worry about electricity or charging them, and for us they typically last until midnight or longer.
