Cables
A cable (also called a cross) is formed by using an extra needle, usually a cable needle or double-pointed needle, to hold stitches to be crossed either to the front (which crosses them to the left), or to the back (which crosses them to the right). The cable crossing is worked on the right side of the work. The extra needle should be thinner than those you are working with to avoid stretching the stitches. After you have worked the cable, be sure to pull the yarn firmly before working the next stitch to prevent gaps in your work.
LEFT AND RIGHT CABLES
The illustrations below show examples of a six-stitch front (left) cable and a six-stitch back (right) cable.
