Aurifil thread is 50 wt. 100% long staple mercerized Egyptian cotton,
good for machine embroidery, quilting and serging.
It's perfect for using in your bobbin as it causes very little lint and, since it is 50 wt.,
you can fill a bobbin with a large quantity and not have to refill so often.
For piecing a quilt, three thread colors are essential:
1. White for piecing white fabric.
2. Black for piecing black fabric
3. Linen for piecing most every other color.
