anyone know of a source of grill cloth for a Danish modern predicta?

[Electronic M]

So I got the Danish modern predicta I scored at Radiofest working * and before I go to JoAnn fabrics and get some random fabric that looks ok from 10' I wanted to know if there is a source for an accurate reproduction speaker grill cloth. Anyone know of one?



* I had to replace most of the wiring harness behind the HV cage with wires from a parts Philco split chassis because it apparently burned up in the 60s and someone snipped out a section and did a lousy job of splicing in new black cloth wire with electrical tape covered in glue... CRT has no ID label....Seller claimed it was a 6.3V CRT in it (tests good like that but has HK short), but the chassis was wired for 2.68V CRT. Heater was dim and picture was a dim smeary mess at 2V heater so I moved it to 6.3V...If the heater don't open I'll take the seller's word as the truth.
