Worked out from Craft Yarn Council, Standard Yarn Weight System and 2 other sources.
Yarn estimated from the yarn-weight category rather than a measured swatch. For an accurate figure, work a gauge swatch, unravel it and measure the yarn it used.

How this is worked out

5 steps
  1. Gauge: 14 stitches and 8 rows over 4 in, so 3.5 stitches and 2 rows per in.
  2. Chain 140 for a 40 in width, and work 100 rows for 50 in.
  3. Estimated from stitch count and yarn weight: about 333 yards before allowance.
  4. Adding 10% gives 367 yards.
  5. At 200 yards a skein, buy 2 skeins.
