I'm doing Dear Jane, too!
I watched Sharon Shamber video on using "light weight foundation" (Pelon fusible on oneside) to applique and would never have tried without it! It stays on the piece and is easy to sew through.
I'm so glad you found a way to help you! Do you know who your vendor is and if she has anything on-line?
Here's the one I use.
I guess this is where one says that we all have to find our own niche to fill. I watched this video a few days ago after finding it posted here and was beyond bored to tears with the whole process! I guess I'M not meant to do this sort of thing, but will admit that the results are beautiful.
