I have always been impressed with Amann products and have used Rasant for years because of its strength and minimal appearance when colour matching the fabric used. In the last year or so I have changed the looper threads in my normal overlocker to #120 Rasant because it improved the appearance and has a smoother finish.
This is worth mentioning.
