Hi, I'm Cynthia Mann and we're here today at Birch Fabrics in Paso Robles, California. This is also the home of Fabricworm.com. Hi, I'm Melissa Lunden; I'm the resident seamstress here at Birch Fabrics. I teach sewing lessons here, prepare blog tutorials and sew samples of Birch's line of organic cotton. And I am here today to talk to you about sewing. Hi, we're going to identify the parts of a sewing machine. This is a basic model that's computerized so it's a little bit different than your mom's machine that you borrow when you were little. But the basic features are the same. You have the power cord. You have the foot pedal. You have the thread spool. You have your hand dial which you always crank towards you. Don't crank away, crank toward. You have your bob and winder. And then you have the thread guide, the thread take-up lever. Here you have your computer settings, and you have your speed. Your thread goes down through. This is your needle. This is your needle crank. This is your presser foot. Beneath the presser foot, you have your feed dogs which are the texturized pieces of metal that move your fabric through the machine. You have your bobbin. This is called the throat of your machine. And when you take this off, this is called your arm. And when you take off your extra little storage case, this makes it a little bit smaller and makes it easier to do smaller pieces of sewing like a cuff. In the back of the machine, you have the switch that drops your feed dogs, which means that your machine will no longer push the fabric through and that something you'll control. And you'd do that if you were doing free-motion quilting or darning. And that's your machine.
