I mark my patterns on my background fabric. I then trace my patterns onto my freezer paper. I then place it on my background fabric and needle turn my fabric under the freezer paper. Somethimes I leave it in and remove from the back after appliqueing it on but most of the time I remove it with tweezers just before I finish the shape. Works for me and saves the steps of applying glue and then having to wash it out. I found this is so much faster. Have been doing it this way for years.
