Dina I would say the 2.5 is probably millimeters. Is yours a European or Asian machine? I think 10 per inch will catch 7 to 10 threads of the materials I have looked at with each stitch. That should be plenty secure I'm hoping. Don't laugh folks. Again, I'm used to high precision metal work with blueprint specifications. I will have to struggle to leave that mode of thought behind......Don
