I use method like “Pokey” said!
But I must add some comments about beginning and the end!
Thread the needle (hardest part)
Take the two ends of the thread and hold them up together so that the needle
is hanging down in the exact center of the thread.
Tie a the two ends of the thread together in a small knot, as close to the top/ends
as you can.
So when you start sewing, making the first pass though the back/underside of the
shirt, needle up through shirt, then button hole, the knot stops the
thread from coming out!
Do as Pokey describes.
Then at the end …
Make the final pass, through front of shirt … through button hole
then through shirt. The needle attached to the thread coming out the
back side/underside of the shirt.
Take the needle tip to the underside of the shirt where the thread is coming out
and put it through/under a few threads of the shirt or the runs of thread you have already
made. Like when you pinch some skin together and put a needle through.
Picture someone who has had the bridge of their nose pierced.
While needle is there “piercing” the shirt, take the thread from between the
back of the needle and the shirt. And wrap it a few times around the tip of the
Then slowly and gently pull the needle out. Continue pulling gently as you
do, the loops that were wrapped around the needle tighten into a nice knot
at the base of the shirt! Wha La! Snip
Easier then it sounds! Hope I explained it well and that it makes sense!
The end is the key! It’s like making a fisherman’s knot, if you can relate.
