Climax Kate, a New Home series L treadle, is finally up and sewing. My struggle is with the tension. Between the upper tension and the VS it is a struggle to find a happy medium. I've even adjusted the presser foot tension to try to remediate puckered stitches.
Are there any strategies that I can try to reduce the amount of puckering? I can get the interlock to meet in the middle but the stitches still pucker!
