Same on upper and lower....but I'm with others, Rayon is NOT a good thread to use on quilts. Tell her to check out
www.metroemb.com and try that thread out. I used it all the time when I longarmed for customers and NEVER had a complaint. The website doesn't say you can use it on a longarm, but I have successfully for 100s of quilts. AND it's CHEAPER!!!!!
