Which Needles and Bobbins are best with Bottom Line™?
I like to use a Schmetz-Microtex #60 needle with Bottom Line™ thread. If you have any trouble at all with shredding or when you are stitching through a lot of seams, try changing to a larger needle or loosen your top tension.
I also like to tighten my bobbin tension so I don't have any backlash with the bobbin. This can happen with a lightweight thread.
To avoid this problem, purchase an extra bobbin case. Then you can 'play around' with the tension and leave the general sewing bobbin case alone. Ask your supplier if you are unsure about what to do to adjust the tension. As you learn to alter both the top and bottom tension on your machine, your stitching will improve.

Can I use Bottom Line™ for the binding?
I find that this thread works beautifully to bind my wall quilts. Use a double thread and a fine needle and the stitches just seem to disappear into the fabric.
So for quilting, piecing and applique, I use Bottom Line™ thread on the top and/or in the bobbin of my machine, depending on the effect I want. With 50 different colours to choose from, I find this a very versatile of threads.
