Cup holder Lid and Phone holder

[audifin]

Well today I did install a wireless charger, decided to put it behind on-off switch so that I can decide whether it stays on when ignition is turned off.

To finish it off I am planning to make a new bottom panel with a cut-out for the phone, which would then stop the phone flying around too. Does anyone know where I could buy suitable material for that? Ideally it should be similar fabric as the tray is now. Have tried eBay but not much luck...
