On a Brother KH260 (9mm) Knitting Machine I used a 3 and 1 cable that was 10 stitches wide.

I haven’t washed it yet so it’s a bit stiff. Will soften up once I wash the wax off that I used while knitting it.

The first picture shows where I joined the beginning and end of cowl. Not perfect but it can be worn in the back and won’t be seen.

I think it’s about 24 inches before washing and blocking.

Sad but true…my daughter wouldn’t model it so she put it on our dog. Cute though!
