I don't have your machine, I have a Bailey. I use Organ 15x1 which is a size 16 needle in mine. These same needles fit my regular Janome machines also if I'm doing heavy duty sewing such as denim or canvas. Superior threads has a great deal of needle/thread information on their site, it might be best to match your needle size to the threads you plan on using, otherwise, follow the mfg. suggestions in the machine manual.
