Insert the end of a 24 inches (61cm) strand of thread through the eye of the needle. Then, pull the end of the thread until it is even with the other end. Tie a knot to secure the ends of the thread. You will need to rethread the needle with a new 24 inches (61cm) strand of thread each time you start sewing on a new button. Push the needle in through the fabric where you marked the pants with chalk. Then pull the thread through the fabric until it is taut. If you want to keep the buttons hidden inside of the pants, then sew through the top layer of fabric on the waistband. Do not insert the needle all the way through to the other side. Just try to catch the fibers on the top layer of the fabric. If you want to place the buttons on the outside of the pants, then you can sew all the way through. After you have inserted the needle through the fabric, insert the needle through 1 of the buttonholes. Pull the thread all the way through the buttonhole and slide the button down the thread so that it is right up against the fabric. Next, insert the needle down through the buttonhole opposite the one you just threaded. Pull the thread all the way through the buttonhole until it is taut and the button is right up against the fabric. You do not need to insert the needle all the way through the fabric. You can just catch the fibers with the tip of the needle and then pull the thread through until it is taut. This is especially important if you want the thread to be hidden on the inside of the pants. If you are sewing the button onto the outside of the pants, then you may catch the fibers or sew all the way through the fabric. After stitching through 2 of the buttonholes 1 time, repeat the stitch to ensure that the button will hold and the stitch will not come loose. Depending on the type of buttons, you may only have 2 button holes to sew through. Repeat the process for those holes 1 time. If your buttons have 4 holes, then you will need to sew through each of these holes twice.
