I did see and read alot of the comments here about weights of thread for FMQ. But, I would like to know : What type of thread is best for FMQ? 100% cotton, Poly, mixed? And do you use the same thread in the bobbin?

I like to use poly embroidery thread 40wt in the top and bottom :D:D:D I get less tension issues with my machines matching the top and bottom thread wt :D:D:D

I use Mettler Silk Finish or King Tut cotton thread on top and Superior Bottom Line in my bobbin when I do my FMQ.

My dinky mechanical brother is not fussy. I've used all kinds, latest being embroidery rayon, coats and clark.

lots of discussion on the board search and you will find it.

I use Sulky silk thread
