Lisa that is great info thanks! :-D
I do use the quilting thread in my machine and have had issues with the fibres gradually clogging up the eye of the needle then the thread snaps. It's not too serious - say on the FMQ of a bed quilt, it happens 2 or 3 times in total. But it always makes me say bad words because of course everytime it happens - that's FOUR more ends to sew in! I've just got some top stitch needles (on the recommendation of a more experienced friend) and am going to give those a try. They have a larger eye so should help with this. :-D
