Three of us working on this cowl for one of our co-workers.
Julibeth , Julie and I are doing the knitting.

I suggest using the German twisted Cast on ( a new favorite of mine), but casting on loosely works, too.

The instructions seem to be written for the Fisherman’s rib worked flat.
There is a link in the pattern which takes you to how to knit the Fisherman’s Rib in the round by Staci Perry.

Here is aother useful link for working in the round: Two color Fisherman’s Rib by Purl Soho.

It’s an easy pattern with nice looking result.
Although I want to add that personally I prefer Brioche to Fisherman’s rib.

The yarn combination from the kit works very well.
Just one more word about the stitch: No need to criss cross your Yarns at the beginning of the rounds.

This was hibernating while my broken wrist was healing, but started it up again on May, 11.
