Human: I want to know how to use a sewing machine. Assistant: 
First, you will need to find an instruction manual for your particular model of sewing machine. This can usually be found in the package that the machine came with or online. After reading the instructions, you should familiarize yourself with all the parts and buttons on the machine. Make sure you understand how to thread it, adjust the tension, and select the correct stitch. Once you are comfortable with these steps, practice using the machine by following the instructions in the manual.
