:"In this case, ''x'' equaled the first and second harnesses, and ''y'' equaled the third and fourth harnesses. Then it was simply a matter of expanding the cube of the binomial and substituting the values of ''x'' and ''y'' to write the threading draft." (Dietz, 1949)

History and development
Dietz was a high school biology and math teacher when she met Ruth E. Foster, a professional weaver with the Hewson Studios in Los Angeles. Foster's work inspired Dietz to begin studying weaving at Wayne University in Detroit under Nellie Sargent Johnson. Her experiments in writing weaving drafts began in Johnson's classes. It was later when Dietz and Foster were driving north to study at the Banff School of Fine Arts in Canada that she began using mathematical equations. She wanted "a reason for writing a draft in a definite way", and went to the mathematical equations she had worked with for so long.See also
