It depends on what type of quilting you're going to do. For example, free-motion quilting would take more thread than say just stitch in the ditch. But generally, you could probably make 3-4 small lap quilts with a single spool.

Not sure if it'll fit your machine, but you could but a cone holder with the arm that sticks up in the air and then thread it over to your machine. I love the large cones and have one of every color that CT makes. Actually, I also love ALL of the CT thread and bought every set they made also. Really nice not to have to worry much about matching thread when I want it!

I believe that's true and the reason I've heard is that polyester thread can cut into cotton fabric over time, like razors sort of, weakening the fabric.
