This pattern is found in the Classic Elite #9105 (soft cover) book, titled "Saturday Afternoon".
I really like the Classic Elite soft cover knitting booklets.
Anyway, the Ariosa is a very plain little cardigan, but the beauty and interest is on the back of it.
A centered lace panel. Very unusual.
I modified the sizing. Cast on for a larger size, and decreased down to a smaller size by armhole bind offs. That's what gives it the slight A shape. Here's what the model sweater looks like.
Here is my Rav notebook for the Ariosa.
