Natural Garden Markers

Well, mostly natural. All you need are some pretty rocks and a Sharpie Marker. I used the silver metallic color because it is what I had in my junk drawer, but I am sure any color would work just as well.

Find the rocks you like, preferably with one flat side and large enough to stay put where you need them. Wash all of the dirt off and thoroughly dry. Once they are dry you can mark them up! 

Easy Peasy. 

Go easy on this picture, I had been digging in the garden for a few hours by this point!
