I think I could use some help here. Recently removed the round point needles that came in the Techsew 4100 machine I purchased, and installed Organ 794 LR Size 230/26 with white 277 thread. First round was a complete disaster, finally managed to get the results shown in the photos. Not certain it is what it should be though, and I can't say that I'm happy with it. Any suggestions on what I should be doing to get this to be a better stitch? Also looks like it is blowing out the back, not a clean exit. One row is just with the needle, the second row has the thread.
