The shawl pattern I knitted earlier was the Plainfield shawl pattern from http://www.yarn.com. I decided to try to knit this in a stockinette stitch pattern. Since the yarn was cotton even with blocking the edge still curled a lot so I added a very simple lace edging... Just 4 rows in the pattern. It added knitting time but I love the look. I knitted the edging onto the shawl as I went.. I found it worked the best when I did it at the end each purl row. I just did a purl two together with the edging stitch and a stitch from the shawl.
