Okay, so it sounds like my thread may be too big. It is the same kind of stuff that MaryTG is using but mine might be bigger, the label isn't on the spool. I also tried a coats dual duty topstitching thread and it wouldn't work either, but as soon as I put in the regular quilting thread it stitched like a dream. So I will work with it some more, this is the 237, I gave up on the others. I have a new Janome I don't want to use with plastic sacks that will sew it no problem so am just not figuring this one out. I guess the thread could be too stiff or something so it won't make the loop for the stitch correctly. I will try some more out, thanks all.
Yes it is the water the bags will be sitting in or getting rained on is why I want a better thread on there. Just thought I would sit down and run these up as it sews so well and it does with the regular thread, didn't know I was going to be all night trying to figure something out. I went through this with the other machines I tried a few weeks ago, I get worn out.lol
Oh it is Mairam that has that cute saying on her messages, Don't let the sewing machine know you are in a hurry, well that is so true
