I was doing some FMQ yesterday and everything was going great until all of a sudden the thread broke and the spool went spinning out of control. When it finally stopped there was thread wound around the spindle. I have had spools of Gutermann thread do this before but never with such speed. I seem to have this problem only with Gutermann thread and I think they must wind it to tightly on the spool so at times it can't be pulled thru the tension and down into the fabric. Usually it will pull itself thru and just spin the spool around slightly and will not break the thread, although it scares you slightly. Has anyone else who used Gutermann thread noticed this. I purchased several spools at a really good price so I will get thru them but I don't think I will be buying anymore Gutermann thread.
