The driftwood came from an old silt fence that was outside at the house we rented a few years ago (and I have an issue with saving crap!)
I used a pencil to mark off 2" spaces. Nailed 1.5" nails at a slight angle at the markings, making sure not to go all the way through the back, and tied a piece of jute twine to hold up the "driftwood."
My husband gave the kids a bath, and by the time they were finished all of these necklaces were FINALLY off my dresser! Woohoo! Small victories. Right?!
