Hi Lee,
If you take the door card off you will see that the fabric part is held in place by melted plastic, kind of like a rivet. I have done this in the past but I can't really remember(5+ years ago lol), wasn't too hard though.
Once you have them out use a glue gun to stick it back in place.
Hope that helps.

Edit: Actually I think I managed to peel a bit off then work around the whole thing. From the back of the door card.
