I am trying to satin stitch large leaves to a tablerunner. There are two layers of stabilizer under the applique fabric. My stitch is not as even or consistent as I would like and I am getting some puckers. Does anyone have advice for how I can improve the stitch or is this stitch just challenging? I could use a small zig zag, but I wanted the look of the satin stitch. Any help would be appreciated.
