Invisible Machine Applique - nylon or poly thread on top, cotton on bottom, blind hem stitch adjusted to do this:
---^---^--- which is stitch/stitch/stitch/bite/stitch etc.
The stitches are small, and placed right next to the applique on the background fabric - and the bite is just single, small zigzag taking one stitch into the applique, but not too deep. I use freezer paper on my applique pieces and turn the edges under. After all the stitching is done I remove the FP by trimming away the background behind the applique. You sometimes have to dampen the area to soften the FP & make it easier to remove.
I've been very happy with the technique for many years. Took a class time ago & it was worth the time. If you googled Invisible Machine Applique you'll find more info. Hope my explanation was reasonably clear. hahaha!
Good Luck!
