For several years I have used Gutermann threads with no problems to my primary machines (electric and treadles). Recently I came into possession of some new 50wt cotton Robinson Anton threads but haven't yet tried them out.
My question is - what thread do you use for your machine sewing & piecing, and why?
I should add the reason I use Gutermann is because this is what my LQS carries and there was no other option.
TIA for your input.
