It is that name weavers in Aubusson call the line of yarn with all the colors they will use on a piece. Mine are very small, in Aubusson, rosaries can have as many as on hundred colors. The one with numbers is Alice and Anita’s, because I planned the colors before weaving and decided where they would be. So I just had to look at my paper and know which color to pick. For Not Matisse, it was not useful, and I just made a rosary in order to keep trace of the colors. For AA2, I will do a rosary, but the colors are roughly indicate on a sketch.
