Took a long time, but I finally finished a pale blue lace scarf of pure merino wool. This could have been a nice stole, but didn't have the patience, I wanted to try out knitting the lace edge directly to the center piece with circular needles. The edge came out quite nice, but of course, this way the scallops are formed by yarn-overs, not solid stitches, and may not hold so well. To give the edge more strength, I added some bobbles (nupps) on the last row.
The Allegretto shawl looks a little similar, though I have used a different stitch pattern, and can be made as a scarf with just reducing the pattern repeats.
