Demalangeni is a triangular-crescent shaped shawl. It is worked from the bottom edge up. The lace border is worked along the full width of the shawl, and then short rows are used to fill in the body with a simple textured stitch that resembles mock cables.

Though the pattern is correct as written (tech edited and test knitted), I admittedly goofed and had to adjust my stitches, which accounts for the random decreases on rows 17 and 20. So adjusting the size, without having to do a lot of your own fudging, may be a challenge. If you want a larger or smaller shawl, and to work the pattern as written, I suggest casting on the following number of stitches:
246, 312, 378, 444, or 510.
Then on row 20, purl 119, 152, 185, 218, and 251 respectively.

About the name, since it seems to be a common question ;)
Demalangeni is the name of a beautiful 12 year old girl that I met in Swaziland, Africa in the summer of 2011. I met her at our church sponsored Care Point where approximately 200 needy or orphaned children are fed two meals each day. She was bubbly and intelligent. Her favorite subject in school is English, and she said that she liked it best because it allowed her to communicate with us Americans. So this pattern is dedicated and shared in her honor. More about my short moments with her on my blog. To learn more about Swaziland, check out BeyondSurvival.org
