I ripped. I started over. This time using size 4 needles. I can get it over my hand now, and am wondering if it is too big. We'll see after a bit. If it is I will probably live with it since the cuff fits fine.
As you can see, I switched the colors.
So far, the fair isle chart is going fine, even though the back side of the mitten is not symmetrical so you have to pay attention. The palm of the mitten is a very easy repeat pattern, so it all evens out.
I'm now worried the red is going to bleed into the white. Never a moment without anxiety. I have no experience with red Debbie Bliss, and I guess I could have "washed" the yarn before knitting, but that seems more than a little complicated and it also sounds like a giant knotted mess waiting to happen. I'll live on the edge and hope.
