Machine sewing thin leather

[MADMAX22]

Question for you guys that sew thinner leather. 

I am making a few smaller card holders and what not where I am  using 3oz for the body and 2-3oz for the pockets (like JLS card holders) and a few other things with similar weights with bridle leather that I split down. 

Using my 111W155 with 92 bonded nylon and a 18 needle (was trying a 19 needle also). 

Issue is it usually does a good job, nice even stitches but with this stuff being pretty thin ecspecially where it gets to the single layer of 3oz its hard to keep the knot of the thread buried in the leather. Most of the time it looks pretty good but occasionally it will either have the knot toward the top or the bottom of the leather. Not the end of the world type thing but I try my best to pay attention to the details on my projects because I want the customer to be happy and unable to point out little things that are not up to snuff. 

Is it that I need to step down in thread size or run a thinner thread on the bottom and keep the 92 on top? Would prefer to stick with 92 all around. Or am I needing to try and fine tune my sewing machine some more? 

Thanks.

try a 16 needle...I use 69 or 92  and with thinner leather it was much easier with the smaller needle.

hope that helps

I have also used a smaller 46 bobbin thread which makes it even easier to adjust the tension
