This may sound a stupid question.. We are currently doing some work on our garden, instead of paving I want to do a pebble mosaic something like the link http://www.google.ie/imgres?imgurl=...m8TdDA&sa=X&oi=image_result&resnum=4&ct=image. I have been looking in B+Q, Woodies and the patio centre and the pebbles there would not really be suitable. Would anyone know where I could source pebbles that are smooth??
