Moving cables around the fabric is surprisingly easy to do by skipping stitches and returning to them. Moved background sts are worked as post sts to avoid holes and are hidden on the WS.
Step 1
Let’s move the cable strands closer together on Row 4 (WS). Turn, using A, ch2, htr in next A st, skip 2 Bsts, FPdtr around next A st, change to B. You’ve moved an A st from between the cable strands to the outside and hidden the move on the WS.
