I just recently discovered a book called Complete Pebble Mosaic Handbook. This is a really beautiful and permanent way to incorporate art into your garden design.A pebble mosaic can be a small touch- a door mat- or an entire walkway. Two artists in particular, Jeffrey Bale and Maggy Howarth are well worth the look. This is right up my alley, obsessive and time-consuming! Let's put some into some San Gabriel Gardens!
