From the Knit Rowan website:

Knit this ladies loose fitting cardigan from DenimThe Next Generation. A design by Martin Storey using Original Denim, a unique yarn that behaves like denim fabric (cotton), this jacket features an all over cable and rib design.

Gauge notes:

• Machine wash all pieces before completing the sewing together.
• Denim will shrink in length when washed for the first time. Allowances have been made in the pattern for shrinkage.
