Tolex Cloth or amp/guitar case (Eubank and Candelaria)

EDIT: I received a piece of a different type of guitar case (Thanks, Colleen!), but I am not sure it will work. It's not QUITE the same material. So, I am going to leave this request open for a bit longer...
Thanks in advance...

I need some tolex cloth, or could instead use cloth peeled off of a busted musical instrument case or amplifier. Black, to match what I am working on.
I am refurbing a guitar case - the person that sold it to me listed it as "well-traveled"! While I am almost done with re-gluing the underlying plywood structure & making some small wood patches, the final steps will be gluing the outer covering back down, then patching the worn spots. That cover is made of 'tolex', that black cloth you see on instrument cases and amplifiers, among other things.
To make the patches, I need a small piece of black tolex, or could peel pieces off of a broken, otherwise unusable case or amplifier, if anyone has anything.
Thanks in advance!
