I found these guys with a Google search. They say bring in your piano, they will give you a free estimate, a wild selection of coverings available. I know, you don't have a Fender Rhodes piano.
https://fenderrhodesla.com/fender-rhodes-tolex.htmlThere are 25 Yelp pages of amp repair guys. Some of them do Tolex, for sure.
There is a trick to it, well several tricks, but this one for sure - spread white glue on the inner portions, contact cement around the edges. That way, you can shift the covering around a bit before putting the edges of seams down tight.
