I used Knit picks telemark and it knits pretty much to guage and so far it looks nice and is really soft. Iam a little nervous as I have never blocked a sweater before so that will be all new to me.
Don't worry about the cables, they are really easy to understand, and even the more complicated ones, they provide a easier one to do that looks similar to the suggested one but more for beginners.
So far Iam almost done the front left collar cables.
I have never knitted a sweater where it is knitted off of a beginning collar.
I really had to read the pattern carefully first and remove all pages not needed as it can get confusing at times.
Anyhow so far so good, I will post a pic as soon as the collar is done.
