Frequently Asked Questions

Q

How much yarn do you get from raw fleece?

Raw wool loses 35—55% of its weight during processing. Merino loses ~40% in washing (lanolin/grease), ~10% in carding, and ~5% in spinning, yielding about 45% of the original weight as finished yarn. Alpaca retains much more weight since it has minimal lanolin, losing only about 22% total.

  • Merino wool: ~45% total yield (40% wash loss)
  • Alpaca: ~78% total yield (10% wash loss)
  • Angora rabbit: ~78% yield (5% wash loss, 12% carding)
  • Cotton: ~72% yield (5% wash, 15% carding)
  • Cashmere: ~50% yield (30% wash, 15% carding)

Cotton5%15%~72%
Q

How many yards of yarn can I spin from one pound of fiber?

Yardage depends on yarn weight and fiber type. From 1 lb of clean Merino (after washing), you get roughly 450 yards of worsted weight, 600 yards of sport weight, or 900 yards of fingering weight. Thinner yarn = more yardage per ounce but more time to spin.

  • Worsted weight: ~28 yds/oz (merino), ~24 yds/oz (alpaca)
  • Sport weight: ~33 yds/oz
  • Fingering weight: ~40 yds/oz
  • Lace weight: ~50+ yds/oz
  • Angora produces the most yardage at ~50 yds/oz due to loft
Q

How long does it take to process raw fiber into yarn?

Processing time varies dramatically by method. Hand-processing 1 lb of raw fiber takes 6–8 hours (washing + hand carding + spinning). Using a drum carder reduces this to 4–5 hours. Sending fiber to a mill for washing and carding brings it down to about 2 hours of spinning per pound.

  • Hand wash + hand card + wheel: ~8 hrs/lb
  • Hand wash + drum carder + wheel: ~5 hrs/lb
  • Mill wash + mill card + wheel: ~2 hrs/lb
  • Fully mill processed: ~0.5 hrs/lb (just plying)
  • A skilled spinner produces 50–100 yards per hour on a wheel
Q

What is the value of handspun yarn?

Handspun yarn sells for $25–80 per 100-yard skein depending on fiber and quality. A pound of merino fiber ($15–25 raw) yields about 4–5 skeins of worsted yarn, valued at $120–$200+ as handspun. However, the labor time (5–8 hours) means the effective hourly rate is modest unless you value the craft experience.

  • Handspun worsted skein (100 yds): $25–$40
  • Handspun lace from merino: $40–$60 per skein
  • Art yarn / textured: $50–$80 per skein
  • Raw merino fleece: $15–$25 per lb
  • Value-added return: 5–10x from raw fleece to finished yarn
