A step-by-step video guide: how to sew a button by hand for beginners First, cut the thread at a diagonal angle to get the sharp point, so it is easier to insert into the eye of the needle. Wax the thread with a candle to smooth the thread, so the thread does not tangle along You can loop the thread in an opposite or diagonal direction of the buttonholes. For this demonstration, we will loop the thread in a diagonal direction. First, thread the needle. Then tie the thread off. Next, place one needle on top of the button. Bring the needle up from the bottom of the fabric through one hole. Bring the needle back down through a diagonal hole. Repeat it 4 loops in the same two holes. Then continue to the next two holes. Loop the thread around under the button, but above the fabric twice. This will make it easier for you to insert the button into a buttonhole. Finally, pass the needle through the stitches, then loop the thread around the needle twice. Repeat the process, then snip the thread
