Janome Machine Needle Guide A ball point needle is made especially for stretch and elastic materials and tightly woven fabrics. The head of the ball point needle has a snake's head shape due to a combination of both a slightly bulged eye and a reduced blade over the eye. The bulged eye opens a slightly larger space in the material and the thinner blade reduces contact between the needle and the fabric. This results in a lowering of needle heat up, preventing skip stitches. The tip is a light ball point to separate the fibers rather than cutting, avoiding needle holes in the fabric. The scarf of the needle is deeper allowing for a larger loop for forming the stitch, eliminating skipped stitches. The needle size should be chosen based on the weight of the fabric.
