I purchased a husqvarna viking 100 just for classes because of the weight and the constant unplugging of my bernina and janome. When computer scams into schools we were told to unplugged and put away every day. These machines were always going wrong. Once they could stay in situ no problems . I worry that unplugging our machines all the time does the same thing.
The above machine has a selection of stitches as well as a good sewing stitch was recommended on create and craft sewing and purchased when on a special offer.
