Indi Report post Posted May 12, 2017 I just bought a brand new Consew 206RB-5 and everything works fine until I backstitch. The stitches indicate tight bobbin tension/ loose upper thread tension, but it looks fine going forward. I'm afraid the items I make will pull out over time because the stitches are so loose. Does anyone know what this could be caused by, or ways to fix it? Quote Share this post Link to post Share on other sites
