I took a machine appliqué class from Harriet Hargrave years ago and think you still may be able to find her book it was not hard turns out very nice we used freezer paper for template ironed on wrong side of fabric cute out 1/4 inch around pieces then used glue stick to stick to freezer tape used blind hem stitch to appleque cut small hole in the back to remove freezer paper if some was stuck to hard spritz with water and on smaller pieces I used tweezers to remove paper through the hole worked very good I also took a class from Mary Stori for another kind of appliqué where you can use a picture off fabric , fish, flower whatever lightly stuff small hole in back use a drinking straw to turn then all appliqué by hand in your wall hanging makes some great picture quilts there are so many ways to appliqué you just have to find the kind you like
