Often overlooked, but nobody can do without it. The under-thread is essential for machine embroidery work. Embroideries in general are a connection of two separate threads, needle and under-thread. Since the stability of such a connection is determined by the weaker component one should consider a suitable under-thread when after all a high-quality top thread is chosen. Of course one could use all kind of threads for this specific purpose, and even more there are many different philosophies about underthread that might suit best.
We recommend:

„The high-class thread“: Saba^c 150, corespun thread PES/PES:
Perfect off-winding performance form the underthread bobbin guarantees the best locking performance. The low thread cross-section makes for a high length capacity and thus an economic embroidering process. Length cap./bobbin approx. 75-80 m.

Art. Nr. 7677; available on 5,000 m cones in 475 colours.

„The nice price thread“: ISA 150, 100 % spun polyester:
Outstanding price / performance ratio plus best quality. The alternative for price-conscious people. Length cap./bobbin approx. 85 m.
