SERAFLEX® is a new to the market innovative elastic sewing thread, it is highly elastic and is perfect for use with stretch fabrics. The secret is its special composition: raw material PTT allows the thread to stretch up to 65%.

We recommend using the sewing thread with straight stitches; use in the needle and bobbin thread with a lower thread tension for maximum stretch.

TIP: Always wind the bobbin slowly to avoid stretching the thread.
