Turn old bottles into plant markers

Some ideas are just asking to be shared more! When I saw a post from Lorilee at Cackleberry Cottage about using wine bottles as row markers in the garden, I immediately thought about giving new life to all types of old bottles by recycling them into iris and daylily plant markers.
Being short on empty wine bottles, I used an empty beer bottle instead.  I wrote the name of my plant on the bottle with a pink, waterproof chalk pen, nail polish and a black paint pen.  Maybe I am a bit compulsive? I do like the pink chalk pen the best but only time will tell which method has the most staying power.  To help the bottle stay put, I pushed a 40D nail into the ground and anchored the bottle upside down over the nail head.
