I used the black speaker cloth from partsexpress...many here will also recommend GoM (Guilford of Maine) fabric...I'm pretty sure they have a true black cloth that is acoustically transparent.
I'm not familiar with the Stewart black (use plasma) so I don't know if either would match...
Cheers,
Rich
