A teaching article describing how a summer session weaving class created new patterns by altering the tie-up rather than the threading. Starting from an 8-harness point twill threading in Spot Bronson, students added plain weave borders, then put spots and diamonds inside the large diamond figures and worked out the matching tie-ups. Over twenty variations resulted, shown in Figs. 1-21, and the article ends by noting that new patterns come from changed threading, treadling, or tie-up.
