I've seen this kind of edging referred to on here, but can't find it now. Apologies for starting a new topic.

I can see that your mates might be concerned that the bottles will break and that the sand might prevent this. If you did fill them with sand, how would you stop the sand falling out of the bottom? Would you put the corks back in? Each one???? Also, if they had corks and sand in then might they get damp inside through capillary action? Could that water then freeze causing the bottle to crack?Ranter wrote:Can I take it then, that all those who have tried this haven't filled the bottles with sand prior to burying?
Sorry to keep harping on about this, but my friends are insistent the bottles should be filled. I don't think it's necessary. They have left it for me to seek arbitration here.
I love the lights idea, but that would have to be for home & I'm concentrating on the lottie for now. Still I can (& do) dream.
