The very first cone I bought I found it linty and it was breaking all the time but I changed my needle and it solved the problem. That was for piecing.
This week end I gave it the real good test with a good size embroidery cleaned the machine first of course and also about half way just in case and it turned out very good.
I had no problem at all
So I think I just been unlucky with that first comne because my embroidery used about 11 colors and had no problem at all :-) So I will definitely continue to buy from them !!
