Description from Knitty.com:

Inspired by the Spanish Dancer sea slug, this design is a mitered, bottom up shawl with a bottom ruffle. Like its namesake, this shawl's bottom ruffle is reminiscent of the beautiful, swirling skirts of Spanish dancers.

The knitting is easy, with decreases only on alternate rows and everything knit in soothing garter stitch. The bottom ruffle creates the sense of a fitted shawl with swirling ruffles to give it weight and shape, and the hand-dyed yarn gives depth and color. The shawl is unblocked, enhancing its body-hugging shape and making it easy care.

This shawl is worked in one piece from the outer most edge to the center, using a provisional cast-on. The bottom edge stitches are then picked up to work the ruffle, while stitches are picked up along the top edge from the garter ridges to form an applied I-cord edging.
