means A traditional stranded-colorwork knitting technique, named for the tiny Scottish island it comes from, that builds geometric patterns by carrying multiple yarn colors across each row.

from Named directly after Fair Isle, a remote speck of land between Orkney and Shetland in Scotland, where islanders developed this stranded knitting style — small motifs repeated in bands using just a couple of colors per row, though many colors across a garment. The island's name itself likely comes from Old Norse, reflecting centuries of Norse settlement in the region, though the exact root is debated. The technique got international attention in the early 20th century, the story goes, after a certain Prince of Wales was photographed in a Fair Isle sweater — but the knitting tradition itself is older and owes more to local wool, long winters, and trade links (possibly with Baltic or Scandinavian knitters) than to any royal patronage.
