If you mis-cross a cable...and discover it many, many, many repeats later...you will be tempted to leave it AS IS...unless you are like me...in which case...YOU JUST GOTTA FIX it somehow. There are methods of fixing mis-crossed cables that involve cutting the yarn in the mis-cross area...not under discussion here.
I mis-crossed a cable in the CUFF of a sleeve...and didn't discover it til the whole dang sweater was seamed!
Here is what I did to fix it...by 'HIDING IT". I took the same yarn...and applied 'lazy-daisy' duplicate stitches over top of the right-leaning cable...it should gone left-leaning! Here is a photo (my pencil is pointing to the duplicate stitches) of the "fix"! Can you tell it was ever mis-crossed??
And, here is a photo of the pullover and me. Easy to see why I wouldn't want to frog back and fix the cuff that way! Even if I had discovered it before seaming! Well anyhoo...I hope 'this remedy' can help you sometime. It may not work in all cases of mis-crosses...but it did for me with this simple, less complex mis-cross.
