Beautifully regular irregularity

Would Recommend

Beautiful! These stones are nicely interlocking in overall outline while being somewhat irregular within that outline, which means they can make either an organic-looking loose path or a tightly tessalated pavement. I wanted the former - a naturalistic loose path, surrounded by smaller pebbles. They worked great!
