Help with making pavlova bases
Pan release spray (such as PAM in the US) can help hold the paper in place (to aid your piping) and prevent the finished meringue from sticking to the paper once cooled. I've used this technique in both professional kitchens and in my own kitchen at home.

Spray a light coating on the pan, then lay down the paper. 

If necessary, spread the coating evenly with your fingers or a towel (for some reasons, the consumer/home versions of these products often emit more of a "blast" compared to the finer "mist" of the professional ones).

Then repeat the process on the top side of the paper.
