muffin papers

Hello all, and hopefully thanks for all the help.

I make lots of muffins at work - savory and sweet ones.
My problem is that the paper always seems to stick to the muffins.
I have just stopped using them, but really would like to use them. I think it makes the muffin look better.

I have tried spraying them muffin pan first, then put in the paper - no luck.
I have spayed the pan and put in the paper and then sprayed the paper - still no luck.

Help please.
thanks
Denise
