I actually posted on the topic of circular garments in knitting in June-August 2011. Hard to believe 2 years have gone by since I last played with this idea. Here is a version knit on the Passap, using tuck stitches both single and double bed, awaiting seaming and blocking (alpaca/silk)

and swatching for a variation on edging with cotton, using rib tuck and slip throughout

This is such a simple idea with very pretty results. I just have to try this for myself. Thank you for sharing.
