May need to buy a yard and cut to size but why don’t you contact customer service for ECS first and see if they will cut it for you. Just a bunch of chatty stitchers here but customer service for this site is super.

If you have white, I can hook you up with a company that sells at a less expensive cost to you. Let me know if that's okay.

You might also try a fabric store. Joann's is pretty good.
