I use a thimble to push needle most of the way through then use needle nose pliers (or regular ones) to pull it the rest of the way!
Tried using a hemostat to tie and decided I'll never be a surgeon! Not strong enough to pull needle through fabric either!
What needles do you all use? I'm using embroidery needles, but have a few very sharp needles about 2" long that I foolishly tossed the packet for!
