Tony - awesome website - easily the best on the net - well done. You've inspired me to lay my own path/patio area (40m2 total) with a mix of 12mm/20mm stones and 60 600x300x50 granite slabs placed 'randomly' throughout.
Question: do I prepare the sub-base & lay the stones first and then dig out area for each granite block or lay the granite blocks first? Cheers
