I love a challenge! If you have ever bought a bag of mixed yarn bits off eBay or Craigslist, found a box of intriguing yarn in a relative's attic, or been handed a sack of random yarn as a gift, you will have eventually found yourself faced with the question of identifying it. What IS this stuff, and what can I do with it?
- Snip off a few inches and pluck at it: how many plies does it have?
- Does it have a "halo" of longer, finer fibers that haze off of it?
- What kind of texture does it have - is it smooth and shiny like an artificial fiber, or rough and grippy like a classic Shetland wool?
- Is it a novelty yarn with odd bits of texture, or a thick-and-thin sort of yarn that might have been hand-spun?
- Is the yarn in a hank, a skein, a center-pull ball, or was it hand-wound into a cake or ball?
- Take a good long sniff. What does it smell like? (Don't laugh! There are 100% wool yarns that smell so much of lanolin, you might think you were smelling a sheep itself. On the other hand, a 100% acrylic yarn will probably smell like nothing at all.)
- What happens when you do this? Does it easily catch fire, does it melt, or does it only reluctantly catch fire and then extinguish itself when you move the flame away?
- What does it smell like when it burns? Burnt hair, burning paper, melted plastic, or something else?
- Does it leave any ash behind?
