Step 1, measure the distance from tree to tree where you want to hang the lights.
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 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.
