I have to say I have stayed away from coats for years had several issues with it years ago while garment sewing, I haven't bought it since, I now believe it was a bad spool but I guess I've gotten spoiled by my gutter an my hancocks only sold mettler and black and white gutter an, but when Joanns opened I bout the 30 pack of gutter an on sale - I only use aura fill for my piecing though just but it online from a cheap source....
