Errata 06 Feb
There were errors in the written instructions for Cas Cables. An update has been sent to existing customers, with changes to the written instructions only, for Cas Cables. The rest of the pattern instructions are unchanged.
The most up-to-date pattern file is titled ‘Cas pattern 06.02’.

Cas (pronounced ‘kos’, meaning to twist in Irish), is a tribute to the National Museum of Ireland’s collection of pieces from the Golden Age of Irish Art - specifically, items made during the 8th & 9th Centuries, featuring interlacing ribbon designs.

It is worked bottom up, beginning with just a few stitches, in single-row stripes of garter stitch. It features interlacing cable motifs worked in both colours, and is finished with an applied i-cord edging.

Knitting this shawl requires some attention and focus: the single row stripes are achieved by working two right-side rows, rearranging the stitches on your circular needle in between the rows. Then the knitting is turned and two wrong side rows are worked. Cables are worked in both colours, using one colour per cable strand. The cable stitches are slipped when working a row with the ‘other’ colour. Cable crossings are worked both with right side and wrong side facing, and some stitches are elongated to prevent the cable pulling in the fabric.

The cable instructions are given in both written and charted format.
If you choose to print this pattern, it may be helpful to note that the cable written instructions are on pages 8 - 10; the cable charted instructions are on pages 11 - 12.
