I have used a type of felt that comes in squares 8″X10″ , and I believe I got it at Micaeles. [hobby fabrics]
The stuff I got came in several colors and it has adhesive on the back.
It is not as long as you need but you can cut strips and also put them on top of each other,
to get the size, width and length that you need.
I have used it on many glass dials that require a padded material between the glass and the chassis.
