The eye of the needle is too small for embroidery floss.. You may be able to get 2 strands in it, but forget about 3 strands, which is what i use..Way too expensive for needles that can't be used for their purpose.. I've tried using a threader, but it just pulls apart trying to get through the eye... I have now purchased 4 styles of the John James needles and none of them seem worth the extra money...
