pieces of stone or tile assemtvl~:ul into a rrs~s~I~le shape for packaging,

A door or wall surfac~;; is p~-~I~areP:l as b~ levelling and then covered with

THE PREFERRED ElVIB01:1fMEN~f
The preferred embodiment of tlae rnc~sai~.: tile assembly c~f the invention is
assembled from irregular de~~~r~~tive pebbl~:5 ~,u~l~ ~xs beach pebbles as
shown in

dimension C.
~Vlultiple such pebbles may bw:: .~~rar~ged into <~ x>~atterw in tl-m tc~rrr~
of a floor or

A cavity 2 is formed in eactn ~~~btrle ato~~~. ~~ ~,u~~~~t~ axis 3 Each cavity
2 is
