Out of thousands of cones and spools there a few that are bound to have a flaw in any brand. Stuff like this doesn't bother me. It's just part of things that happen. I may have paid good money for the thread but I find great almost steal bargains that save me good money so it evens out. I always think when a frustrating bump comes along then I'll have a good bump coming too. It never has failed to be true for me.
