Trees are natural supports for decorative outdoor string lights, especially if you have them on both sides of a grassy area. Learn how to string lights across the backyard correctly, and your lights will look like they’re floating in the air after dark.
 
Step 1, measure the distance from tree to tree where you want to hang the lights.

Step 2, consider how tight you want the lights pulled as you measure. Taut lights give more structure, while looser ones feel more casual.
 
Step 3, drill guide holes on the trees where you want to hang the lights. With a helper, string the lights from one tree to the next, holding them carefully to make sure the holes are the right distance apart. Mark the spots on the trees and drill guide holes.

Step 4, install a hook into each tree at the marked spot. Install the bulbs in your string lights.
 
Step 5, thread the string lights onto the hooks. Make sure they’re securely in place.
 
Last but not least, connect your string lights using an extension cord if needed. Check to be sure your string lights work properly. If necessary, use an additional hook to secure the string lights firmly against the trees.
