I only do machine applique. I may be the only person on the planet that doesn't actually care for the way needleturn looks and is willing to admit it in public. I wouldn't even consider doing any applique until I discovered fusible web. I use several different edge finishes depending on the look I want. Larger black blanket stitching gives it more of a folk art look. Matching thread in a tiny blanket stitch gives a very elegant look. Straight stitch with invisible thread is a cleaner, more modern look. Straight stitching with either matching or variegated thread is also more of a modern look. An interesting stitch for the edges of leaves is a blind hem stitch with the v's pointing out. The one stitch I never use is satin stitch.
