Organ home serger needles 15x1SP Size 14 recommend to reduce deflection which can cause needles to hit metal parts

Recommended Size 14 Regular Sharp point is the default from the drop down menu, unless you select Size 11 for lighter weight fabrics and threads, or BP Ball Point for knits.

This is a special version of the 15x1 for stretch or elastic materials and tightly woven knits. It is made to higher standards, it has a snake’s head shape due to a combination of a slightly bulged eye and a slightly reduced blade above the eye. The bulged eye opens a slightly larger space in the material and the thinner blade above the eye reduces contact between the material and the needle. This reduces needle heat-up and prevents skip stitches. It is also available in a light ball point to separate the fibers rather than cutting them, avoiding needle holes in the fabric.

For Babylock, Bernina, Brother, Elna, Juki, Pfaff, Singer, Viking, White and any home serger the uses flat shank rather than round shank needles.
