Sorry, can't help, but just wanted to say that I am a real fan of Lopi.
I knitted several Icelandic jumpers when I was a student, and even managed to make a few pennies by selling them. I still have a couple that I wear through the winter, 25 years on. They are so fast to knit (all plain stitch and no sewing up), and I used to be able to knock out a jumper in 2 or 3 days.
I would love to knit another one but I am afraid that the internet has killed any passion in that area. Rather than sitting watching TV in the evening with hands available for craft work, they are now busy on the keyboard.
