A general purpose needle that can be used on knit or woven fabrics. A casual sewer who might repair a pair of jeans today, a child's t-shirt tomorrow, and some lingerie next month. You will probably use this needle most often. It will do a number of tasks sufficiently. It has a long scarf that is great for zigzag stitching and it does not damage knits. It is sharp enough to go through a lot of fabrics but it does have a slight ball point which does not make it ideal for going through many layers or high thread count fabrics. The shank(top part) of these needles have one flat side and one rounded side. These will fit all "household" models of Brother, Janome, Singer, Pfaff, Bernina, Viking, Elna, Kenmore, Baby Lock, Simplicity, N, White and many others.
