Terri, Over dying used to happen a lot probably 12+ years ago. I am not sure it happens much anymore. Try polyester thread and if you still have problems try changing the needle number you are sewing on or check your design. I can have a look at the design for you at no charge if it is happening with a particular design. Anand Just some musing for this afternoon.. I understand that black thread is the weakest due to the over dying. Are spools of thread weaker nearer the cone or outside? If so, is it only on certain colors? Does it matter for 1000 M vs. 5000 M cones? Terri Embroidery Creations -- No virus found in this outgoing message. Checked by AVG Free Edition.
