if you go back to the michael miller site- there is a customer service- contact us- link- when i was in search of a fabric that was almost 10 years old i contacted them- they were wonderful and even sent me the names of a couple shops that actually still had the fabric.... when all else fails try going to the source and just asking-
there is also a fabric search site- you can scan the fabric send it to them and they put out the feelers---a great way to locate fabrics! i (think) there is a posting here on the fabric search site.
