you're welcome Amanda...
sorry about the crappy pictures.
Example is a 6 stitch front twist cable, twisted every 4th row. Do not attempt cables until you are comfortable with ribbing.
Step 1)work in p6,k6 rib for 4 rows. (remember that for ribbing you knit on the Right Side and purl on the Wrong Side, so row 2 will be k6, p6, k6)
Your purl st will be your background and your knit stitches are your cables.
(picture swatch shows only one cable, and not all 6 purl stitches on either side)
Step 2) p6, slip the next 3 st Purlwise onto your cable hook or dpn and let hang in front of work.
Step 3) remember to move your yarn to the back and knit the next st on the left hand needle. Pull tight.
knit the next two knit stitches.
Step 4) The twist. Slide your stitches on your cable hook or dpn to the right side.
Knit the next 3 stitches off the cable hook or dpn as if it was your left hand needle. The first stitch you slipped should be the first stitch you knit.
Step 5) Bring yarn in front and purl next 6 stitches. Repeat twist for each cable (set of 6 knit stitches)in this row.
Step 6) Next 3 rows treat as p6,k6 rib. 4th row repeat cable twist (this should be a RS row).
(finished cable twist plus two more rows)
