In visual design, rhythm is the use of repetition to tie together design elements. Several elements share a distinguishing feature that relate them to each other (image 2.)
A yarn contributes to the rhythm of a fabric by how it combines repeated design elements of color, size and texture. If the primary yarn in a fabric has regular color changes, the fabric will show varied color. If it has occasional strong elements like a bright color, slub or knot, these will also show in the fabric. The overall effect the yarn has is dependent on the frequency of changes in the yarn, the construction technique and the size of the complete fabric: a weft yarn with long lengths of changing colors will generally show larger areas of solid color in a narrow woven fabric than a wide one, and in a large gauge knit than a finer one. Different yarns with similar design elements combine to contribute to the rhythm of the overall fabric, which may be so large in relation to the yarn that many individual characteristics are hidden in the scale of the design.

Examiner 2 commented that I did not discuss the "overall contribution" to four specific types of fabric construction.
