When I returned from my travels, did all the laundry, sorted through all the mail (real & virtual), I sat down with my knitting. In a large basket with a partially finished knitted afghan and 27 skeins of Noro Kureyon, I spied something that looked suspiciously like a clothes moth. Time for action! I spread everything out in the sun and fresh air for the rest of the day, turning blanket & skeins frequently. No signs of damage. I will keep a close eye on things for a while. Most of my yarn stash is non-wool, but you never know.
This very clever knitting pattern, Ten Stitch Zigzag, is the creation of Frankie Brown, and is available as a free download on Ravelry.
