The Arch Bridge Kerchief is slightly curved triangular scarf/shawlette started from the longest (upper) edge and worked with short rows thereafter. Choose any yarn from fingering to worsted according your taste - the yarn and needle choices naturally affect the final size and yardage of the scarf/shawlette.
The gray and off white scarf/shawlette has been knit using Novita Florica. The green and orange scarf/shawlette has been knit using Wollmeise Twin, ending up in slightly smaller dimensions.
The Finnish version has been extensively test knit. The English version is already available but still under test phase.
