As I quilt and from time to time I have to knot the ends and bury them. Trying to get 2 or more threads thru the needle eye can be tricky but I found if I fold the ends over and push the looped section thru the eye, I have a better shot at getting it to go thru. It never fails how the thread ends like to unravel on you and doing it this way eliminates those unravel ends........at least for me.
