The Diminishing Rib Cardigan from the Spring 2009 issue of Interweave Knits. Based on other knitters' comments on their finished cardigans, I decided to knit at a tighter gauge than recommended and expected it to grow signifigantly during blocking. It didn't though, so it's a bit smaller than I expected. My stitch count is from the 35 1/4" size, but the dimensions are smaller due to the gauge difference. Sideways, I was able to stretch it somewhat, but the tightness of the slip-stitch I-cord edge puts a limit on how much you can stretch it lengthwise. I do like how neat the edging looks, though. And even though the tubular cast on was a bit tedious, and the tubular bind off didn't feel so much fun at first, either, I like how they look and will probably use them on future projects. Unlike many other knitters, I do not feel the need for any kind of closure for the front (possibly because mine is smaller than the cardigans that stretched too much).
Edited to add: Last night in bed I suddenly realized I forgot to mention the yarn and needles used. The yarn was Berroco Ultra Alpaca (in a shade called Gordoba Grape) and the needles 3.5 mm circulars.
