I substituted the Artyarns SR for the Fiesta Yarns La Luz called for in the pattern. Using a larger needle, I got a slightly larger scarf. Artyarns SR is a silk/mohair combinatation with a glitter silvery thread running through. The pattern is available free through Interweave Knits, Summer 2006, also online for free.
There are 8 panels of arrowhead lace, separated by bands of stockinette. No matter how hard I tried, I couldn't capture the halo of the yarn, the soft variagated grey and mauve bands of color, and the pretty silver glitter of the yarn in my photos! This scarf was started and almost completed on my vacation - it was a perfect take along project.
