I use a satin stitch, or the one that is straight but has a quick sideways stitch (not the blind hem) for my applique'. I use a fusible web - iron it to the back of my material I wish to applique', cut it out and then sew on. I have had very good luck with this, and since it is a little thicker than the material I an sewing it on, I don't need a stablizer. I usually match the thread, or will do a varigated if I want more contrast.
