This is for anyone with information, might be a long arm quilter and might not be. I am just asking here since there is such a wealth of information in this site. I am fairly new to long arm quilting and I get a small loop on the topside every once in a while. Not a lot, almost like one little stitch isn't tight like the rest. I have checked everywhere for dirt, nothing. I have not messed with the tension much as it doesn't occur very often. Maybe about 6 times on a whole big quilt. I would love any suggestions that you might have as I am getting frustrated by this. Thanks so much.
