Aurifil's 50wt 2-ply thread is their most versatile and popular cotton thread. The 50wt thread is strong and thin, and results in remarkably flat and crisp seams. 

While it's wonderful for machine-piecing, subtle quilting, top stitching, and English Paper Piecing (EPP), it also works well for needle-turn appliqué, machine appliqué, machine embroidery, dense machine quilting, longarm quilting, and basting.
