The pattern is the Heartstrings (Jackie E-S) Triangles within Triangles shawl. I knit it on US6 needles with Heritage Yarns tencel: one strand of a color called Days of Wine and Roses (black, purple, red) and one strand of solid black. I did extra repeats to make the shawl bigger. I estimate that I used about 1,100 yards of each color.
But wait! There's more! I won a blue ribbon for a vest for my husband. It's made with Cascade 220. The cable is 16.8 in Harmony Volume 5, "220 Aran Stitches and Patterns."
I also won two more ribbons: a second place for a doily and a third place for a scarf. The doily is Christine Duchrow 87-3, found in the third volume of the Lacis collection of Duchrow patterns. What's interesting about this doily is that is has a cable in it! A cable! Thanks to the talented René for charting this doily. I knit it with Cebelia size 30 on US0 needles.
