Hello fellow Minimalist Cardigan Knitters-
I'm jumping on the bandwagon. I finally received my fall IK just last week and was immediately taken with this pattern. I had some yarn on hand for an abandoned project and it seemed like fate. I've knit about 5" of the back so far.
I'm using Morehouse Farm Merino 2-ply in "Olive." This yarn is considered sport weight and since it is a lighter weight than the pattern suggests, I'm following the pattern as written for the 43 1/2" and hoping to get around 38". (Sort of what Bronwyn did, only in reverse.)
I'm looking forward to watching all of your sweaters grow!
