Wine bottle border

We've always wanted to do this.

I did get a little zealous with the digging in. We have made more segments of this border since then - they run between three half-wine barrels containing blueberry bushes, then in a 20-foot border we've about half-completed - and I buried them a little shallower so the "wall" would be more pronounced.

I'll post more photos to the Gardenaut Flickr group when the project is finished!
