I saw these images on Pinterest a year ago and have been collecting ever since.
I think the path paved with bottles could be hazardously slippery, and after all, who would want to dig in that far to plant bottles or risk broken glass under foot? I really love the look of the bottles used for edging. There is just one issue, and that is pesky mosquitoes. We have a pond a yard away, and in warm weather, I have to spray the yard and we run from house to car or barbeque grill. My Delicious Sweetie is a gourmet treat for those critters, and he can't get more than a few feet before swarms of them attack. So, what to do about those concave bottoms inviting water to collect and offer breeding spots for more critters? I then thought of this image that I also love and blogger cathgrace has kindly given us a DIY for.
There is another issue. My yard has lots of old oak and gum trees. Our yard is lower than the others and years of rain run-off has left little workable topsoil. Anywhere I dig is an impenetrable mass of tree roots. I don't intend to fight nature, so I plan to wabi-sabi and do imperfect edging here and there, wherever I can dig a bottles in.
...Those balls I bought at the Dollar Store! I had the bag on the floor and the Sweetie happened to bump it with his foot and an amazing thing happened. Please pardon the blurry photo.....
...So, I examined it more closely and realized it is filled with a liquid that will probably break the ball in freezing weather. I will have to go back for other balls, but isn't that just the coolest?
