Guaranteed Passage Kit
The theme for the 2026 Chicago Yarn Crawl is a celebration of 100 Years of Route 66. We chose Wooldreamers 90 Varas for our project, the Guaranteed Passage kerchief, because the sheep that made it are experienced travelers.
90 Varas is sourced from Spanish flocks that still travel the ancient drove roads following the rhythm of the seasons. Flocks that move, that graze, that care for the land without even knowing it, simply because it is their way of life.
The name 90 Varas refers to the traditional width of these historic routes which is about 75 meters wide, the width that guarantees passage for full flocks to journey across the country.
Kit includes:
(3) 50g skeins of Wooldreamers 90 Varas yarn, (1) skein each in colors A, B, and C
225m / 246yd, 50g per skein
100% transhumant merino wool
There is enough yarn in the kit to make the kerchief and the coordinating hat included in the pattern.
Note: The coordinating squared zipper bag shown with the yarn in some photos is not included with the kit. It's available for purchase here!
You will also need:
needles:
- US5 straight or circular (kerchief),
- US6 16" circular and dpn’s (hat)
stitch markers: 2 (kerchief), 6 (hat)
tapestry needle
pattern: available on Ravelry
