It never fails. Whenever I go to the park, for a hike, & sometimes even a drive down the road that I notice carved initials inside of a heart. At the park the initials have been hastily scratched into the top of a picnic table. In the woods the initials have been painstakingly carved into the trunk of a tree. A nearby bridge overpass spray painted with the initials. Perhaps it's cliche, but I'm drawing inspiration from those carved initials.
Available at justforkeeps are Vellum Luminaries with a carved look.
