Stitch length is 2mm have used both 138 and 207. The thread is from leather machine company. Not sure of the brand though, it is what they supply. I have the thread going through the 2nd hole down which is straight on from the thread feeding it. Still trying things but still encountering knot pull through.
it’s almost like it doesn’t matter how thick the material is. It still pulls through. The tension is super loose at this point. Very bizarre.
‘’I appreciate everyone’s responses as I work through this.
