You can't use Press & Seal on paper...it will stick to your paper pattern and ruin it (been there, done that). It is sticky and is great in your kitchen...no need for all those lids anymore. It will seal, release and re-seal.
It will do the same with fabric. As stated above, you do have to take it out of the stitches. however, I've found it to only be a problem if my quilting pattern has close stitches. Otherwise, it doesn't take long...for me at least. I use a hat pin to loosen an edge and then grab and pull...none of my stitches were ruined nor came loose in the process...but that's just my experience..I can't speak for others.
Again...some kind of plastic overlay in order to trace is necessary because it will ruin a paper pattern.
Also...if you can draw, you can lay the Press & Seal right down on the place to be quilted and just draw your pattern directly on it. This stuff is a great way to preview a quilt pattern, even if you don't use it for anything else.
And it's cheep...always a plus.
