Oh my....I'm making Amused (again) but continuing the cable past the join and I messed up AT the join...about three cable turns back (these are reversible cables).....I've never fixed reversible cables before and the last time I fixed cables was years ago and I had my extremely talented niece help me. Heaven hep me!
My best advice is vigilence. I ladder back to fix cables if at all possible so if I keep constant watch after every twist, I limit the damage. Very pretty sweater (no wonder you're repeating the pattern) and nicely done reversible cables.
Whew! so glad that worked. It does take time but it seems like such a triumph to finally get it all fixed. Don't worry too much about the loose sts. They'll work themselves into the sts on either side.
I've yet to screw up cables but when I get to them these tips will be much appreciated and in the meantime, I can apply and practice what I've learned on other, simpler stitch patterns. I love the way questions I didn't even think to ask get answered here!
I should never overestimate my basic arithmetic skills.
