Gemrm,
Don't get the wrong impression from what I wrote. I have used the starch method on a few things and it does work well once you get the hang of it. For some, it doesn't take long to do so and I have many friends that use this as their preferred method of applique. If you want a crisp finish, it does the best job. Many of the things I am working on now and in the recent past look better with a softer curved edge. If you are familiar with Pearl Piereira's works - Baltimore Christmas, Baltimore Halloween, American States Album [dont know if this is the right name...] She has hundreds of pieces in her blocks, some extremely small and much easier to deal with when using the starch method properly.
I think it is a good idea to try many different methods and use what you are most comfortable with depending on what you are making.
