Thank you! I have seen those.
The alpaca one might work, if I can replace the ribbon with elastic.
I also really like the cabled one, but I need a more modest neckline, and long sleeves. I'm a new knitter, so I'm not so good at modifying pattern. I can make some changes...maybe. But I can't imagine that I'll do a very good job modifying a plunging neckline. It would probably come out puckery or uneven.
I also found a nice one (2 actually) at Annies Attic, but it is a cardigan. I'm sure there is a logical way to turn a cardigan pattern into a pullover pattern, but since I'd actually like to wear the result in public, I'm not sure I'm ready to figure it out.
Maybe if I buy the yarn at my local shop, the owner would help me a bit? (Or maybe not--last time I was browsing in there, they were complaining about customers wanting THEM to recalculate the pattern for a different gague.)
