Question: what does cb4 mean in knitting?
Answer: E.g. cb4 translates to cable back four (a four-stitch right-twisting cable). This means you will slip two stitches onto a cable needle, hold these at the back of your work, knit two stitches from your left-hand needle and then knit the two stitches from the cable needle. In total you will have knit four stitches.
