The History

The yarn is named for the Worstead village in Norfolk, England. As far back as the 12th century, this town produced smooth, even yarn and was a hub for spinning fiber.

Wool Processing and Spinning: Worsted vs Woolen:

The word “worsted” doesn’t always refer to yarn weight. It also means a wool processing technique — the worsted method, instead of the woolen method.

The worsted process involves combing the short hairs out of the fiber. The same length fibers are spun parallel to each other, making a dense yarn.

What Knitting Needles To Use

  • Metric Needle Size Range = 4.5-5.5mm
  • (American) U.S. Needle Size Range = 7-9
  • United Kingdom Size Range = 8-6
  • Knitting Gauge Range in Stockinette Stitch to 4″ – 16–20 sts
  • Crochet Hooks – 5.5–6.5 mm s (I–9 to K–10 1/2)
  • Lace knitting – size 6.0mm-8.0mm
  • Knitting socks, potholders, or dish towels – 3.25-4.0mm

  1. I have trouble finding yarn that behaves as worsted wt yarn used to. And it always errors to the skimpy skinny side. My guess is that manufacturers are going for yardage and count on most people knitting scarves and Afghans

    • Hi Karen. Craft Yarn Council states yarn labeled Aran and Worsted are the same weight. Always do a swatch to check your gauge meets the pattern requirements. Cheers Jodie

  2. Aran is 100% Wool & is itchy especially to my Grandchildren. What Yarn is good to sub for this that is soft to the feel in the Worsted Yarn. I have an Aran Knitting Pattern for a pullover Sweater my Grandaughter wants me knit. She is age 8 wears a size 7 USA sweaters . Question is would a size 26-28 inch Aran size be a good fit for her.

    Appreciate any advice you can give me. Thank you. Christina.

    • Hi Christina. Try acrylic worsted weight yarn (like Red Heart Super Saver, Cascade Cherub yarn, or Caron’s Simply Soft). Comfy Worsted is a 75% cotton/25% acrylic yarn from Knit Picks. Any yarn substitution should be swatched first. Before knitting the entire sweater, wash and block the swatch. As far as what size would be best for your granddaughter, I’m no expert, so I’ll ask my readers. Cheers Jodie

    • Hi Christina. I asked on Ravelry, as there are many knowledgeable and knitters. Here are their responses:

      – I’m knitting a cardigan for my granddaughter, who’s 8. Since I don’t see her often, I work from measurements her parents send me. Her chest measurement is only 21″, so I’m doing the size 26″ chest. I have to knit the body and sleeves longer than the pattern calls for. I asked for the length from wrist to underarm and underarm to the bottom of the cardigan. It’s hard to get her parents to measure her! After I sent my granddaughter a tape measure, she asked them to measure her and send the measurements back.

      – Additionally, how quickly does she knit and how complex is the pattern? Since it’s July, she has several months before she can wear it. Some of us have multiple projects going, which can influence the timing. Some aran knitting can be fairly simple, especially if she’s using a thicker yarn. Worked in a lighter weight yarn, a complicated pattern may take a while. Could you encourage her to join Ravelry so we can talk directly with her? We don’t bite! And we love to help.

      – If your reader can’t get an actual measurement, the (US) Craft Yarn Council says a 26-28” chest measurement is Child Size 8-10. But since kids grow so quickly, err on the side of slightly bigger-than-current measurements.

      – You might make it with a bit more positive ease and the sleeves and body a bit on the long side – or knit the sweater so the hem and cuff are worked downwards so you could lengthen if needed.

      Hope these help. Cheers Jodie
