Identifying Unknown Fibers in Your Stash

by

yarn burn testYesterday we looked at our odd balls and organized in terms of yarn weight. Maybe you already have an idea of some yarns that you’d like to go together in a project. If so, that’s awesome!

But sometimes you need a little more information about a yarn before you dive into using it. And with unlabeled balls the thing you may still want to know is what kind of fiber you’re dealing with.

Sometimes you can tell a bit by touch — at least enough to know if something is a natural on manufactured fiber. Sometimes you can tell cotton (or at least something in the cotton/hemp/linen family) by the feel, and you can often feel something and know it’s made with at least some animal hair. stash busting

There’s no 100 percent surefire way to determine what every unlabeled yarn in your stash is, mostly because there are probably blends, and a lot of the fibers react in a similar way when you test them.

The most common test for determining what kind of fiber you’re dealing with in known as the burn test, because you set the yarn on fire and see what happens.

Of course you’ll want to do this in a safe place, away from children and animals, with a protected surface and using only a small sample of the yarn.

Set it on fire (I use a long lighter) and observe. What happens to the fiber? Does it burn or melt? Natural fibers (and rayon, since it’s made from wood) will burn, while acrylics and synthetics melt. How does it smell? Wool and the animal fibers smell like burning hair, as you might imagine, while cotton yarn and similar fibers smell like paper or leaves. The manmade fibers can smell anything from vinegar to fish to chemicals, and they usually give off black smoke and leave behind various interesting residues.

I’m not a huge expert on burn testing, so if you want to try it for yourself you’ll want to check out more detailed information at FabricLink and Fiber-Images.

If you’re still wondering what something is, or you just don’t want to go to the bother of testing, assume what you have before you is not machine washable. Or knit a swatch (which uses more yarn, yeah!) and launder it the way you might want to launder something made out of the yarn. If it felts or something else drastic happens, you’ll have learned something valuable even if you don’t know exactly what the fiber is.

Have you tried a burn test or another method to learn about a mystery fiber? I’d love to hear about it!

  1. My mom taught me about this, but then, she’s got a degree in chemistry. Whenever I try it myself I end up getting flustered and and up not noting the crucial bits.

    It’s fascinating stuff though.

  2. I have used the cholorine bleach test on yarn. Wool or animal fibers will completely dissolve in a couple of minutes. Pour a small amount of bleach in a small glass dish and cut 2 or 3 inches of the yarn and just drop it in it the dish. If it doesn’t all dissolve, it is a blend.

Vintage Bed Socks Knitting Pattern – A Cozy Little Gift Project With Old-Fashioned Charm

There is something wonderfully nostalgic about a pair of handmade bed socks, isn’t there? They are practical, pretty, and just the sort of project that feels like it belongs beside a cup of tea, a good film, and a basket of wool that is pretending not to be overflowing.

This vintage Bed Socks knitting pattern is one of those sweet little patterns that still feels useful today. Originally from the Jaeger Hand-Knit Series No. 44, the design features a simple garter-stitch foot, a ribbed cuff, eyelet holes, a crochet chain tie, and little tassel-style pom-poms at the front. The original pattern even describes them as “a very acceptable present,” and honestly, I don’t think much has changed there.

These would make a lovely handmade gift for someone who is always cold, someone recovering or resting, or anyone who appreciates a bit of old-fashioned comfort. They would also be beautiful as a Mother’s Day gift, a winter birthday present, a Christmas stocking filler, or a “just because you deserve cozy feet” project.

The pattern itself is delightfully simple in construction. The socks are knitted flat, beginning at the lower edge, with the foot worked in garter stitch before moving into the ribbed upper section. The decorative eyelet row allows for a crochet chain cord to be threaded through, and the finishing tassels give the socks that charming vintage look. The top edge is finished with a row of double crochet, which adds a neat handmade touch.

The original measurements list the socks as approximately 10½ inches from the top to the lower edge of the heel, with a 9¾ inch foot length, and the pattern notes that the size can be adapted. As with many vintage knitting patterns, modern knitters will want to check gauge carefully and choose a soft yarn that feels comfortable against the skin. A cozy wool blend, soft acrylic, or washable yarn would all work depending on whether you are making these for everyday use or as a special gift.

I especially love that this pattern has that “giftable” quality without being a massive project. It is small enough to feel achievable, but still special enough that the finished pair looks thoughtful. And let’s be honest, handmade socks with pom-poms are always going to beat a last-minute candle from the supermarket.

The PDF version has been cleaned up and formatted for easier reading while keeping the original vintage design intact. It also includes a modern pink mockup image and the original vintage scan, so you get both the historical charm and a fresh idea of how the finished socks could look today.

If you enjoy vintage knitting patterns, cozy handmade gifts, or quick projects that feel useful rather than just decorative, this sweet little bed socks pattern is a lovely one to add to your collection.

You can find the Vintage Bed Socks Knitting Pattern PDF in the CraftGossip Etsy store.

For supplies, this is also a nice stash-friendly project. A soft yarn from Mary Maxim or Amazon would work well, and if you make pom-poms regularly, a small pom-pom maker is one of those inexpensive tools that saves a surprising amount of fiddling.
