If feathering is a problem, you will have more success with a closer satin stitch edge. If you don't want to do satin stitch (I perfer buttonhole) a smaller needle may help. I also like to use a heavier black thread, Sulky Premium 12 wt. cotton. I make sure the part of the stitch that goes along my applique runs right on the edge with the black thread covering the edge. I don't know if it comes in different colours because I like the black. I always use Wonder Under for my applique and remove the center portion. It can still be a bit stiff and I want to try Misty Fuse on my next project. Hope you can get it worked out and maybe someone else will have more hints for you.
