I am doing a massive appliqué project at the moment and I am doing fusible raw edge. I did some research and everything I read showed that it should hold up fine no matter what kind of stitching you do around the edge. (Though I think satin, zigzag and blanket would hold up the best)
I am doing free motion straight stitch around my shapes but I'm going around each shape 3 times. So even if you weave around a bit it still looks like you did it on purpose!
Here are some pics

(Straight lines are basting stitches. Background will be free motion stipple. I'm not quite up to the circular swirls in the pattern!)
