Compared to 50/2 weight thread the extra number of twists in the 60/3 weight coupled with the 3 strands gives it extra strength. In practical terms, when piecing with a 50/2 it may be necessary to reduce the stitch length to get a good strong seam whereas it is not necessary with the 60/3 thread. Use as a bobbin thread and for hand or machine applique. 600 metres per spool.
Harriet Hargrave, the well-known and respected machine quilter teacher, has endorsed the thread. "This thread is your answer to gaining back your seam allowances, it is very thin but strong! Use it for quilting too, when you are quilting more than 2" apart" For piecing the taupe (362) or light grey (352) are recommended as they work with most fabrics.
