Rayon is notoriously weak and is often not colorfast. I would not use it for quilting. If you love shiney thread most trilobal polyesters will fit the bill. You should consider Glide, Superior Magnifico, Isacord or Metro Embroidery thread. The metro site carries Metro and Glide. The Metro is very reasonably priced and the colors are very shiny.
