Strip cutting with hardwood guide and scrollsaw.
Squares can be cut from thin woods for the logs for rosette tiles. With care the pattern can be laid takeing the layers and dipping the ends in glue and setting one on top of the other. If you are going to make a lot of one pattern then take 2cm wide by 10cm long, strips of colored veneer and glue them until you have one layer of the pattern you desire,continue making the rest of the layers. Then saw them and assemble the multicolored strip assemblys into the tile log. The log is then cut as one would cut a sausage to make the tiles.
