Dear Jan,
Is it absolutely necessary to use only Janome bobbin thread in the bobbin for memory card embroidery, or can I use any standard sewing thread? -Anonymous

Dear Anonymous,
You should not use standard sewing thread in the bobbin, as it may not be the correct weight for machine embroidery. Superior stitch quality is achieved with Janome bobbin thread. The weight of the Janome embroidery thread [which is 60/2], was designed specifically for embroidery. This thin, smooth, strong thread is the correct weight to use in the bobbin, with Janome Embroidery thread in the needle, for a balanced stitch and professional looking machine embroidery. The incorrect weight bobbin thread can cause the bobbin thread to show on top of your embroidery.
