Jean, I'm not sure what to tell you so maybe some of the others can offer some advice.
When I use freezer paper for needle-turn appliqué, I fuse it to the FRONT of the fabric and lightly trace around the paper with a pigma pen for my turn under line, then remove the FP to do the needle work.
When I want to use a stabilizer on the back of the appliqué, I use Stable Stuff because it can be left in the project, and there is nothing that has to be removed.
The best advice I can give at this point is to either use tweezers to remove the paper before it's all stitched in place, or securely stitch all the edges then carefully cut open the background fabric and remove the paper from the back.
