Thank you Dave, that is a big help. Kind regards

I am new to machine embroidery and now need to buy some bobbin thread. There seems to be so many different types and I'm looking for help. I am currently using Brother 90wt polyester which isn't giving me any issues. I've seen a 150s 5,000m cotton/polyester which would be more cost effective and I wouldn't have to keep buying thread but I don't know what the 150s means or what weight it is. Help in deciding which thread to use would be brilliant.
