There is a method where you use the interfacing for appliqué.
You trace the appliqué shape on the smooth side of the interfacing. Then put the interfacing bumpy side to the right side of the appliqué fabric and sew along the traced shape. Cut a small slit in the interfacing and turn the little 'pillow' right side out. You can then place the appliqué where you want it on the background fabric, give it a fuse and then stitch it down using your chosen method. This way you have finished turned under edges, like with needle turn, without the exacting labor.
