That is exactly what I was posting for help with a few days ago. I just couldn't get a picture posted to show it. My first project (in 2003) was microspun and it did EXACTLY what Beldie's pic shows!
I'm not alone! Unfortunately, I'm seeing this twist in other things I've done. It isn't as noticeable with heavier yarn, but my merino sock yarn has a vicious little twist in it, too. My LYS says that my knitting technique is great, she thought maybe it's a question of tension. Yvonne, can you do a test to see if you do this with other yarn? I would really like to know what the heck is happening with my yarn. It occurs in both English and Continental. I think I'm going to call the Schoolhouse Press people and ask for help. (Elizabeth Zimmermann's posse) It will take me a couple days to get to this, but I'll let you know what I find out. UNbelievable! This forum is GREAT!
