I recently finished B
amboo from DanDoh Designs in a nice lightweight cotton yarn.  The yarn is 
Filatura Di Crosa Kady in white and in a variegated green.  My yarn is a finer gauge than the specified yarn and I knitted the 46 inch size to achieve about a 40 inch width.  I was going for a 21 inch length but got about 22 inches.  This is a very loosely knit style so it drapes very well.  I didn't add any sleeves and I also did some shaping on the front neckline so that it curves down lower than the back.  This is because I prefer to have at least some front scooping on my necklines instead of the more flat boat neckline look.   I could probably have curved it down even more.  I finished all the edges with two purl rows after picking up stitches and bound off in purl.  I used a decrease bind-off to achieve a little more stretch.
This sweater is great now that the weather is warming up so I plan to wear it a lot this spring and summer.  I'll wash it after a few wearings and it might shrink a bit but that would be fine.
