I finished the sweater, and it's blocking as we speak! I have only the tiniest bit left (of the yarn I thought I'd run out of)--wound up, it's smaller than a golf ball, maybe more like a walnut.
Here's what's weird: I used a Zephyr Jaggerspun, a 50/50 wool silk blend, and Forever Lace, from Spunky Eclectic, that's labeled as 100% merino, with instructions to hand wash. Nothing there sounds like superwash, right? But when I wet-blocked it last night, it acted like superwash--stretched a good 4-5 inches in length, seemed floppy and kind of lifeless, etc. (wet-blocking in this case means I soaked it in cool water, rolled out the excess water in a towel, then patted it into shape on a towel and left it to dry.)
I thought about putting it in the dryer last night, when it acted like superwash (superwash wool often needs to be machine dried to bring it back to normal), but then I reminded myself that I was tired (and perhaps a little unhappy about my now too big sweater) and that I should just go to bed and see what it looked like it the morning.
It was the same too-big size this morning, so into the dryer it went. And whoosh, it came out the right size after about 10 minutes (I didn't let it dry completely, just got it from the drier side of soaked to slightly drier than damp). So, hurrah!
On the other hand, how weird! Could one of the yarns be superwash without me knowing (and despite the label)? Was it the silk (and if so, how? It was less than 25% of the yarn)? Gnomes who like to make you nervous but not actually ruin anything?
In any case, I can't wait to wear it to Rhinebeck (Where I will take pictures! And then write a proper project summary!)
