We switched from Arc Poly to Isacord and it made a 95% improvement not saying we never get thread breaks on black but sure has helped. I had tried 3 different spools of Arc Poly before I switched so I don't think it was just a bad spool. =========================================================== The AmayaUsers Mailing List Website: http://www.amayausers.com Discussion Board: http://www.amayausers.com/boards Subscribe/Unsubscribe: http://www.amayausers.com/list ===========================================================
