Yes, I have unravelled the mitts. What a surprise!!
I didn't like the way the sewn seam looked so I unravelled them to the point just above where the writsband is sewn in, and have continued to knit them in the round using double point needles. Much better!
And, even better than that, I have enough yarn remaining to finish the second wristband. Yay!
Now, if only I had remembered to get some buttons when I was down the hill this morning.....
