Many stitches are known by their common names, which are often taken from the first extant find. However, there have been several to create nålebinding notations.
The notation developed by Hansen is probably the easiest notation to understand. U=Under and O=Over.
There are also notations by Hald and Nordland, but these are not as comprehensive.
