Java Moss Carpet With Cotton Thread Fabric

I was intrested in making a do-it-yourself fish tank carpet with Java moss but was worried because cotton is considered Degradable. I think that would be a good thing for plants but not sure it will be a good thing for the aquarium. Can Anyone confirm I will be OK making a cotton fabric carpet Java moss? 100% cotton

 

Cotton thread will end up falling apart but if tge moss is tied to something it will attach itself so it doesnt matter

 

Thanks that was what i was hoping.
