I was going to suggest some of the destashing groups on FB but I see your (beautiful) fabric is 385gsm92/8 and most of the fabrics offered in these groups is 95/5 and around 200gsm. So not sure whether they'd do the job. I've had good quality jersey from pepe_monty on eBay at, I think, £7/m delivered but it's not anywhere as thick as yours.
