Does this give you enough info to define the cable stitches?
That is only part of the cable pattern... the part where you do the cable 6 stitches to the back....which is done by placing 3 stitches on a cable needle (a DPN can be substituted for cable needle) move those stitches on the needle to the back of your work, knit the next three stitches...then knit the three stitches form the cable needle (or DPN). then follow the rest of the pattern until you reach the next c6b. Several rows further along you will be directed to do a c6f which is worked in a similar manner...except instead of placing the first 3 stitches (on the cable needle) to the back of the work, you will move them to the front of the work, knit the next three stitches then knit the three from the cable needle.
