My Brother doesn't seem to like Rayon thread. It usually does pretty well with polyester, but I have this one spool that just doesn't work well with the machine. It (the top spool) all winds up around the lower bobbin, then gets tangled up in the craziest places and in the feed dogs. If not caught almost immediately, it pulls the bobbin up and out of the case and pops the design out of the stabilizer! One bobbin looked like a mad dog tried to eat it! :(
SO, my answer to your question is to try several different brands at first to see what your machine likes. Then, go shopping on eBay for that particular brand.
