There is now Errata for this pattern. It has been corrected here already and appears in italics. If you printed this before 1/2/2013, please use this updated version instead.

The Puff Rib Cowl is meant to be roomy and non-binding. It works up quickly, so it is an excellent last minute gift. The simple Puff Rib stitch adds an interesting texture that imitates cables without the extra bulk.

The fabric is very stretchy when worked in wool. It has not been test knit in cotton or silk, so the results in a non stretchy fiber are unknown for now.

If you desire a closer fit, cast on fewer stitches by reducing the stitch count in multiples of three. Conversely, if you want a larger cowl, to pull down over your shoulders perhaps, cast on more stitches in multiples of three until you reach your desired width. If a longer cowl to cover both your head and neck is what you want, just keep on repeating the Puff Rib pattern until the optimal length for you is reached.

Gauge:
17 stitches and 20 rows to 4 inches in the Puff Rib pattern with yarn held doubled. The gauge is actually a bulky gauge. Bulky yarn, such as Yarn Geek Fibers Dyed and Plied, could be easily substituted. Just cut the yarn amounts in half.
