When I do needle turn, I use a bent beading long handle tweezer the fold the edges under, hold the turned under piece in place with my non quilting hand and stitch away. It works awesome for very fine stemwork and leaf points as well. I also use the freezer paper method sometimes too. I just do not care for all the prep with the starch, etc. You can also have used the freezer paper templates with shiny side up on back of fabric, cut fabric slightly larger and press edges to freezer paper. It works best for me if I put a pin in the center of the piece to hold it in place while I press the edges down.
