Unusual fiber content:
Silver (yes, the metal, though it doesn't look at all metallic): Zaol BioRope contains "mirawave" which is a silver-content fiber that is supposed to lend the yarn special properties such as being antimicrobial and conducting heat away from the body.
Jadeite (yes, the rock known as jade!) SWTC's "Therapi" is 30% jadeite.
Vicuna, Qiviuk, Guanaco yarns and blends: the yarns were heavenly and so were the first-rate crocheted samples in the booth! (At the website some of the crocheted designs are called "knit".) Here's a hairpin crochet wrap in handspun qiviuk and silk; here's a qiviuk wedding dress.
Milk fiber: Kollage's "Creamy" in icecreamy colors!
Recycled soda bottles? There is a new polar fleece yarn and I can't remember its name nor could I make it to that booth but Marty did and I love the projects she crocheted up already. The yarn looks great crocheted and has all the best qualities of chenille with none of the drawbacks! Hopefully she'll comment here or blog about it herself.
Z-twisted yarns: the yarn is plied with a counterclockwise twist, whereas many yarns (in the US anyway) are s-twisted, which is clockwise. Yeah, I'm the only one I know who actually has a thing for z-twisted yarns. Call me weird, but when I really like the way the yarn makes my stitches look and there's zero splitting, the z-twist is often the reason. (Lefties might prefer s-twist.) When I spot a z-twisted yarn I buy it because I know that even 20 years from now, if it's still in my stash, I'll still enjoy crocheting it.-Two ShibuiKnits yarns: Highland Wool Alpaca; Merino Alpaca.
-Plymouth's Oceanside Organic.
-Be Sweet's Bamboo. 100% Bamboo yarns usually split on me so I've been anxious to try a z-twisted one. There's also a z-twisted bamboo blend called Naturallycaron.com Spa.
-Two Zaol yarns: the silver-content BioRope (see above) and the lace weight 100% tencel Olive.
After attending previous TNNA shows where designer inquiries were not always welcome (as Stefanie mentioned in her blog today), I didn't even bother asking for samples of the above yarns to swatch with. Now that I've blogged about them I wish I had!
