In "Rotary Riot" ( 1991 Judy Hopkins and Nancy J. Martin) in the section on utility quilting (p 111) there are instructions for crow footing (a type of isolated fly stitch, like embroidery) and other tacking techniques. These are different from the big stitch technique previously discussed here. I've had good results with big crewel embroidery needles and size 10 crochet cotton. It's a fun and fast way to finish quilts without tying knots. Hope this helps.
