Um, hello, love this. So cute! So easy! How adorable does this set of string lights look with white heart doilies attached to it? Darling. And so easy and inexpensive. Just punch the light through the holes already in the doily, and you're all set. Could definitely see this in a rustic, whimsical barn or ranch setting.
