From the pattern:

Castilita, or little castle, is a smaller and lighter version of its namesake, Castile. The shawl is an overall Shetland triangle shape with a gentle curve added in the Stockinette Sections, and binding off happens as you make pointed flags across the live stitches at the end. Knit on smaller needles, the shawl makes a great neckerchief, and when knit on larger needles a lovely, warm shawl.
