Wine bottle terracing

You have a problem. You like the odd bottle of wine but due to the lockdown the recycling centres are closed and you don’t want the empties to go to landfill. What is the solution?
My brother came up with a novel one: use the bottles to terrace the steep banking at his house. He has just finished the first terrace which took him longer than he thought. Not that there was a shortage of empties but removing labels and levelling the bottles in position was more difficult than anticipated. Now for the next terrace - behind the first.
Need to imbibe a few more cheeky reds and perhaps incorporate some solar lights.
