Best thread for Bernina 240
I've been quilting for awhile, but still consider myself to be a beginner! Just bought a used Bernina and the former owner said not to use cotton thread as Berninas do not like cotton. This doesn't fit with all other advice I've ever read about quilting, i.e. use cotton thread for cotton fabric. I've used Connecting Threads cotton for other projects with my old Brother machine with no problem. I would appreciate any advice from other Bernina owners!
