Dropping entire rows

20.5 inches up the back, I found a weird zig zag in my work. This has happened before, and I've been like, okay, whatever. But in my infinite curiosity to figure out what had happened, I decided to tink back a bit. I had dropped a stitch.

So I pulled the stitch up.

Only to find that by pulling this stitch up, I had another dropped stitch, TWO rows down. WTF?

I try again. Pull up two rows, inspect the threads....Wham. Another stitch slips down. Three rows. As I'm pulling that back into position, one of the threads turns into a gargantuan 2" loop shooting sideways out of the left side of the work.

So now I'm in dropped stitches, a gaping hole in my work that I will never be able to fix with a crochet hook, and about to cry. I had just semi-successfully changed yarns and had maybe an hour's worth of work left to do on the back when this happened. I go to bed.

This morning, I frogged four rows. (But you had only dropped three, you say, right?) The reason I had to frog four rows is that when I got to the dropped stitch, the working yarn did a U-turn in the middle of the row and headed back.

I had dropped half a row. I have no idea how I did that, but I had.
