Some new information at a Bernina class. The needle threader may be bent with a 75 size needle and probably bent with a 70 needle. My fav has been 70 but with my eyesight, I need the needle threader. For quilting I prefer sharp/microtex over universal. Tostitch and quilting needles are also OK. Schmitz has loads of info re their needles on their webside: shape of point, length of eye, the shaft.....
