In this tutorial, we learn how to thread a horizontal sewing machine. Start off by setting the spool on the top of the machine and placing a cap on the top to hold it on. Next, thread the string through the thread guide and then through the number one. After this, it will go down through the slit and end up at the bottom. It will go through the number two, then go up to the top and go through the number three turn. Once you reach the bottom of the machine, thread the needle, then put the bobbin in. After you do this, you will be able to sew what you like and enjoy your machine!
