I use fuible to applique. I have tried a few different stitches, satin stitch, looser zig zag, straight stitch, decorative stitches. I prefer to use stabilizer with mine. I was doing a doll quilt and forgot the stabilizer behind a couple of pieces and noticed a difference. I like the smoother look that stabilizer gives. For that I use stitch and tear. I usually try to match the color of the applique, but if I was using a multicolor print and didn't want the distraction of the color stitching, I'd use Sulky Clear Poly thread. I did use it on one quilt and was quite suprised how nice it was. It's not stiff like fishing line as the nylon is.
