This is beeeeaaauuuutiful!!! I am sorry your are having problems. Would Stitch Witchery work to anchor the loose edges? How about a glue stick to hold it in place to stitch it? I have a book that uses that techinique, and there are several tutorials on you tube that do also. I am just a novice at this, so just throwing out a few thoughts. Good luck. This is truly a piece of art and too nice to abandon!
