Managed quite a nice job on mine and it has held up for over a year now, no fading and one incident of sagging but my fault for not using enough spray glue (suffice to say there is now a cut Mark where i had to split and reglue it.

)
Used some black heavy felt stuff, came to about £40 for fabric and 2 tins of evo stick spray glue. there are photos in my photobucket.
Considering getting another tray at some point and doing a better job now i know what i am doing.
