A interfitting stamp set for faux finishing includes a number of differently shaped stamps, wherein each stamp comprises, in a preferred form, a rigid backing, a handle applied to one surface of the backing, a layer of resilient foam material adhered to an opposite surface of the backing, and a rubbery ink transfer element adhered to the foam layer, the ink transfer element having an irregular pattern cut in relief on its surface away from the foam layer. The set is characterized in that the various stamps are all different, and have irregular peripheries comprising crests and valleys which nest at least partially within the crests and valleys of neighboring stamps when the stamps are placed together, whereby patterns with overlapping envelopes can be applied, without overlapping the stamps themselves.
