I've seen TV commercials for E Z threading needles for hand sewing. (they have a notch in the head and the thread slides in).
Yesterday I saw them at Joann's for sewing machines too.
It seems to me they would be weaker and bend easily (if used on a sewing machine), also maybe snag the material while going up and down so fast?
Has anyone used them?
My old eyes could use some help since the needle threader on the machine doesn't always work.
