Desperately seeking arm rest cover for 2011 Five, NOT V

I am finally getting around to installing Covering Ballistic seat covers and there is no arm rest cover included in the set. Nor do they make one. I have been looking all over the internet and there seem to be very few options aside from making one myself. Does anyone know of a manufacturer for this year and model. I’m really bewildered by how few choices there are.
I appreciate any help or leads.
