Hope that you will heed the great advice from the above posters and start small instead of buying in bulk initially and learning that you, or even more importantly in my opinion, your machine, doesn't like the thread. A while back I bought a large amount of beautiful thread from Metro Threads. It works really well with my Janome MC11000, but my Baby Lock Sophia doesn't like it a bit. She will only tolerate Robinson-Anton. That makes me really wish I personally knew the poster above who noted that she had thrown away all of her RA thread. Almost made me cry!!!
