Yarn with sections having different aesthetic characteristics, articles comprising same, and methods of making said yarn and articles

A method comprising:

• tufting, knitting, or weaving a plurality of yarns through a backing,
• wherein a first yarn of the plurality of yarns comprises an engineered yarn structure having:
• a first yarn section formed by a first yarn segment;
• and
• a second yarn section formed by a second yarn segment,
• wherein the engineered yarn structure comprises a transition junction that comprises commingled portions of the first yarn section and the second yarn section, wherein the transition junction has a length of less than 1 millimeter,
• wherein a severed end of the first yarn segment is wrap spliced, mechanically knotted, twisted, or entangled with a severed end of the second yarn segment to form the transition junction,
• wherein the first yarn section has a first type of a first aesthetic characteristic selected from luster, color, size, or texture, and wherein the second yarn section has a second type of the first aesthetic characteristic that is different from the first type.
