Here's a little something I whipped up from the Fall 2009 issue of IK. I knit this open front cardi, the Berry and Bramble, in about 2 weeks with about 6 hanks of Berroco Ultra Alpaca Light (Could be 7).
-I intended to make somewhere between the 34" and 37 1/2" sizes. My gauge was slightly larger than called for, so I made the 34", which turned out around 36" or 37".
-I decided the ribbing at the bottom would be too long, so I made it about 7" instead of what the pattern called for (I believe it was 10")
-Upon reading reviews on Ravelry about the sleeves of this pattern, I decided to make my sleeves about 2-3" smaller around than the pattern called for. I'm glad I did this, and escaped having wings.
-I added another half inch to the ribbing for the collar.
The one thing I would do differently is cast off the collar looser (and I could still go back and do this). It curls a bit because it was cast off just a wee bit too tightly!
I'm also not sure if I like how it looks on me - it's definitely a bit boxy, and it shows! They say the camera adds 10 pounds, right? On a possibly related note, I just started couch to 5k a couple of weeks ago - hope I stick with it.
Thanks for takin' a gander.
