Here is a collection of Kayan tattoo blocks documented by Dr. A. W. Nieuwenhuis during his expedition to Borneo in early 1900s. I would like to post it here, because it clearly shows the size of the shoulder rosettes in relation with the arm motifs. The Kayan took pride in their craftsmanship, and have the greatest admiration for beauty. I hope to find a better picture than what I have now. But even with the following picture, one can see the excellent workmanship in the details of the rosette motifs.
