I've finished the Cabana Tee, and I can't say enough good things about the pattern and the yarn. The pattern can be found in the latest Knitscene, the Winter 07/Spring 08 issue. It's simple, easy, and flattering. (Fits my goals.) Although it called for Four Seasons cotton, I used Berocco Touche for the bodice, teaming it with Berocco Soft Twist that I recycled from another top. The Touche color is Lemon Meringue, and the Soft Twist is deep purple. I used a size 6 circular needle, and knit it in the round from the top down, the easy way. It took me about a month, but could probably be done in a couple of weeks if it hadn't had to share my attention with a couple of other knitting projects.
As far as modification, I only made one. I added minimal waist shaping, placing a double decrease at each side twice, then a double increase an inch or so lower. That bit of a decrease provides a little dip in the waist. I did change the sizing to 36", but that wasn't difficult enough to consider it a modification.
The rest of the shaping is due to the drape of the fabric. Both yarns have rayon content, and the Soft Twist is heavy enough to pull the bodice down. Together they make a comfortable, soft summer top. The little cap sleeves are great. I hope they will make the sweater wearable most of the summer. (The mountain summer, that is. No matter what the cut of a sweater, I find worsted weight hand knits too hot for most summer days above 80 degrees.)
