I’ve knit these twice and the right mitt appears off center. Could it use an added stitch or two to center it. The left mitt is fine. Is the pattern off center? Thanks so much for the help! 
One cable fingerless mitts pattern help
The pattern looks like mirror images to me. The placement of the thumb being the difference. If you need an extra stitch or perhaps better, the shift of sts either side of the thumb then go ahead and do that.
Thank you. Am I correct in thinking that if I want to move the mitten to the right I would add stitches to the beginning of the gusset?
It depends on which way you think the mitten is offset. Add or even better shift sts to whichever side of the gusset will center the cable.
Shifting a stitch from the palm to the side of the gusset (arrowhead) will center the cable (direction of arrow).
Thank you, I will try that.
Here I am again. What if on the right mitt pattern I K5 and then K16? I’m trying to wrap my head around this. I think I need to move the entire gusset?
Thanks again!
You want to move the sts between the gusset and the cable. Keep the gusset in place and shift the cable pattern to the right.
For example on the 1st round of the right mitt you have:
K3, p2, k6 (the cable), p2, k2, kfb, M1, kfb, k15.
You can shift a stitch from the palm to before the back of the hand sts.
K3, p2, k6 (the cable), p2, k3, kfb, M1, kfb, k14.
or even a shift of 2sts if you think that’s necessary:
K3, p2, k6 (the cable), p2, k4, kfb, M1, kfb, k13.
Thank you so much, I think that’s what I want to do. I just couldn;t figure it out.
Let us know how it’s going. It’s kind of weird that the mitt seems shifted but maybe it has to do with how the increases are worked? Anyway, good luck and keep us updated please.
I can’t help with fixing this, but just an observation which might explain a shift.
It seems on the pattern pic there are 3 rib columns (3 sets of k2) leading into the cable. On your left mit it looks like you have 3 rib columns leading in. On your right mit it seems you have 2 columns leading in. Possibly you were a few stitches off centre when you started the cable?
I would like to figure this out so I can keep using this pattern as I like knitting it. It’s great for gifts and works up fast. The photo shows the pattern increase instructions. If I see this correctly the instructions for the increases are to the left. I used that increase instruction on the right mitten which would move it to the left and consequently be off center? I think from now on no matter what the pattern is I will use increases to the right and left for both mittens. I’ve ripped out the mitten to the rib. I am grappling with either moving the stitches as you suggested or trying the M1L and M1R. It was suggested that I only used 2 rib columns on the right mitten. But this has happened twice and I did follow the pattern. What are your thoughts? Thanks again for your help!
I think the M1L and M1R are better choices for the increases. Kfb is easy but it never seems as organic or as symmetrical as the M1 increases (or lifted increases LLL or LRL).
You could knit a small swatch and try out the M1 increases to see if you like the look. They should work the same way for both mittens since neither area involves the cable. That swatch would be a good way to identify the source of the shift. If you don’t like the M1s here then go ahead and shift the stitch.
(I have a problem with round 1 of the increases where you work kfb on either side of a M1. That seems to me to be a difficult round to work but once past that, going to M1L and M1R seems like a good choice. The mittens I’ve made usually have a stitch between the initial increases on round one.)
Thank you. I will try that. The stitch between the first two increases is interesting because there is a small hole where I bet an added stitch would close that hole. Hmmm.
