Who You Calling a Micron?

What's a Micron and Why Should I Care?

A micron, abbreviated with the Greek letter µ (mu), is a thousandth of a millimeter.* It's used, as you may have guessed, to measure really small things - like the diameter of the fibers we knit, crochet, spin, and weave with! A red blood cell is about 5µ in diameter.

Why does it matter? While humans can't easily see the difference between a 20 µ and a 30 µ fiber, we can definitely feel the difference. Finer fibers with a low micron measurement usually feel softer and smoother. Coarser fibers feel prickly or even itchy.

Fun Fact - most people who find wool garments itchy aren't actually allergic, they just have skin that's very good at sensing thick fibers. They usually don't find really fine wools, like those from Merino or Rambouillet sheep, to be itchy at all. (True wool allergies are rare but very serious, including a rash, peeling skin, and respiratory symptoms.)

Here are the micron measurements of many common fibers used to make yarns:
Human hair**— 60-80µ
Merino Wool — 17-22µ
Rambouillet wool — 20-26µ
Corriedale wool — 24-31µ
Romney wool — 31-40µ
Generic wool — 25-28µ (most knitting yarn labeled simply "wool" is in this range)
(There are coarser wools used for outerwear fabrics and even coarser yet that are used for rugs)
Alpaca — 15-45µ (most sold for knitting yarns are under 25µ)
Cotton — 11-22µ
Cashmere — less than 19µ
Linen/Flax — 12-16µ
Hemp — 16-50µ (yup, it's a huge range!)
Silk — 10-13µ
Rayon — 11-22µ
Acrylic — 15-25µ

*science wants us to say micrometre/micrometer instead, but science doesn't always get it wants.
**okay, we don't make yarn with it usually, but it usually finds its way into your project nonetheless.

The Tip Jar

What is a cable needle? It's a small double pointed knitting needle that is often bent into a U-shape or a hill-and-plain shape. To use it, you work up to the place where your cable will be, then slip the first set of stitches for your cable onto the cable needle, let the cable needle hang either in front (for a left-leaning twist) or in back (for a right-leaning twist) of the work, knit the second set of stitches for your cable off the regular needle, then pick up the cable needle and knit the slipped stitches off of the cable needle, thus making the sets of stitches switch places.
