Today I have started on my first sweater. It's going to be a seamless Icelandic yoke style done in blue and green heathered Lopi yarn. I am going to use the Zimmerman Percentage System to get the sizing right and pretty much make it up as I go for the color patterning. The nice thing about Lopi yarn is that the knitting goes quickly, since the yarn is so bulky! I pretty much have the ribbing for the body done already.
UPDATE: I now have the body over halfway done.
UPDATE 2: I'm now working on the sleeves, using the same 2-on-2-circs technique that I've been using for socks. I'm past the forearm shaping and into the straight stretch up to the underarms.
