Why should I use prewound bobbins when I can wind my own?
Good prewound bobbins are wound by high tech machines which provide a smooth, uniform wind. The result is much more thread on the bobbin than a self-wound bobbin. Whether you're in the middle of an embroidery design or a quilting or sewing project, having to stop to change the bobbin is always an inconvenience.

Should I tear off the cardboard sides?
If the bobbin fit is too snug to accommodate free rotation, take off the cardboard sides. This will not affect the function of the bobbin. If your machine has an automatic bobbin sensor, leaving on the cardboard sides will make the sensor think the bobbin is always full and will therefore not provide a low bobbin warning. The solution is to either tear off the cardboard sides and use the sensor or to leave the sides on and sew until the bobbin thread runs out.

Is there a difference between plastic sided and cardboard sided bobbins?
Either type is fine. Plastic bobbins are reusable; cardboard bobbins are disposable. Because the plastic-sided bobbins are so smooth, they may continue to spin even after your machine stops and cause backlash. Some machines seem to work better with the cardboard-sided bobbins because the cardboard sides provide more friction and backlash is usually not a problem.

Filament poly. This thread has a shiny appearance and is virtually lint free. It can be thin and lightweight, yet strong. Embroiderers love this thread since it creates a soft backing, even on dense designs. Many machine quilters like using a filament poly thread in the bobbin. Due to it's slick surface, it works well with metallic threads and heavy cotton threads. The slickness of the filament poly thread does not snag or grab the top thread. If you've had trouble using metallics or heavy cotton threads, a slick bobbin thread may solve some problems.

Cotton. Quilters love it. It keeps the fiber content consistent with the fabric, batting, and top thread. For embroidery, it is OK, but on dense fill designs, cotton bobbin thread will result in a stiff design. Beware that lower quality cottons produce more lint which in turn requires more frequent machine cleaning. Choose a good quality bobbin thread.
