Help with stitching consistency

I have a question for you Frank: When you are stitching, are you working towards yourself or away from your self? If you are stitching towards yourself (your hands coming closer to your body when you progress in your stitching), then it would appear to me as though your prick marks are angled in the wrong direction. I could be totally wrong, but could that be one element of what's going on? I stitch towards myself like many others, and because of this, I have my prick marks angled up-and-away from myself.

This might not explain how the left side of the picture (the vertically oriented seam) looks good while the horizontally oriented seam is amiss. Only thing I would be able to think of here is perhaps you started a new thread and switched direction? It looks like the left side of the picture is the front of the stitches, and the top of the picture is a rear side (where I can see your awl orientation is changing slightly).

If none of this proves to be true and you have figured out what your primary problem was, I would love to hear it! I'm am quite curious.

First image is front side of stitching and the second is the back side. Any ideas on how to correct this?

I rotated the piece in the clams because not sure how to move around it.

Hundreds of variables could have caused this, but if you pre-pricked the holes on the panel, it could be as simple as the holes on the handle ends not lining up exactly. If this happened on the right side, it would explain why the thread is off. If my guess is correct, you could remove the stitching and go through the holes again with an awl or a 2 tooth pricking iron and try again.

Of course it could be other issues such as not turning the piece in your clams as you stitch around a curve, varying your technique, changing your stitch sequence etc.

From the picture, for me, the left side is acceptable. The right side is where you have a problem.

This leads me to think that something changed once you reached midpoint and moved your piece around to continue stitching.

you obviously know how to saddle stitch with angles as the left side is like it should, the thread sit in the edges of the pricks with proper angles (maybe a bit more consistency in your pull tension in the future, but that is for later).

The right side on the other, the thread is going from middle prick to middle prick. The only time i see this result in my work is on the backside of the stitch when I do not cast.

Im sorry, i know the above do not help you, i am just thinking out loud hoping it might give you a hint to what you did that is causing this,

Could you film yourself stitching?
