This merino wool -olive green Cardigan is mine and I knitted around 3 years ago and hardly wore it.
I never liked the plain band around the neck. A collar was badly need it, but I kept posponing until last week.
Also it was a tag short, so it need a mayor alteration.
A small yoke I add in the shoulders, which required full unpicking of the sleeves and shoulders.
Luckily I kept the left over. This way it grew a bit, just to the hip bone, where I wanted originaly (some calculations went wrong)
But with some hours of effort......here it is just the way I wanted!
