Khipu Notes:
1. Sample is exchange from the Museum fur Volkerkunde, Berlin.
2. The markers on primary cord are thread-wrapped sections.
3. The primary cord is patched immediately after cord #49. It is possible, since cord attachment changes (from r to v) at this point, that the primary cord was broken after cord #49 and then mended. In this scenario, the mended section (bearing cords 50-59) could have been reversed, thus accounting for the change of attachment direction.
