Found at the start of almost every knitting pattern, this instruction tells you how many stitches to place on your needle to form the foundation row. While the abbreviation is standard, the method used can vary; knitters often choose between techniques like the Long Tail, Cable, or Knitted cast on depending on whether they need a stretchy, firm, or decorative edge. Mastering a few different versions allows you to tailor the start of your work to the specific needs of the garment or accessory.
