actually I do the corners or turns by hand. maybe it is a matter of momentum - using the wheel by hand but quickly and with a bit of force???

once I have the tension set suitably, I find that while sewing curves or corners the stitch becomes uneven - what gives?

I have actually increased the pressure foot today to see what the effects would be and the seem to be above satisfactory. Since I am self-taught, could someone indulge and let me know about the logic of this in regards to my problem. Thank you. Also, I have found the best results with bobbin tension at 100% and thread tension at 150% if that makes sense???

Thank you for all the input. My setup is a JUKI DL-1181N Using Scmetz needles NM:130 SIZE:21 Thread is size 40 - I'm not sure on the conversion - I think its metric. I am sewing 2 layers. I have decreased the presurre foot so that there are no nasty marks left.

I only have experience with much softer leathers - lamb and cowhide. I have a particular veg tanned leather that I want to stitch with my machine but have trouble setting the correct thread and bobbin tension. My problem is that if the tension is too small the stitching is loose at the top for a few stitches and then at the bottom for a few stitches interchangeably. To get the stitch alright I have to set both tensions really tight - I mean really tight so sometimes the thread breaks mid seam. I can't for the life of me get it right. The leather is 1.5 mm - 4 oz. veg tanned leather and is very stiff. If anyone could help me out I would really appreciate it.
