Ok, so I'm doing Samurai Knitter's sweater KAL, and I'm really looking forward to it. I have the wool (Melandra wool rich DK in a dark teal colour) and someone to make it for (Chris).
So, to answer the questions in the first post:
It will be a pullover with a high zip/ribbed neck and full length sleeves, and no shaping.
No idea how long it needs to be, I'd better go find a sweater of his and measure it!
I might do hems for the cuffs and bottom welt, rather than ribbing.
I think I'm going to use the DK double with 5.5mm needles (I often do this for sweaters, so they don't take too long!). Next stop - the guage swatch!
