Look at the hole the needle disappears into. That piece of metal is the plate. If the needle goes down into a round hole, you are using a single stitch plate. If the needle does down into an oval hole, you are using a zigzag or buttonhole stitch plate. Sometimes, when using the plate with the oval hole, the needle will push the fabric down below the plate and you'll get puckers and knots and all kinds of stuff that will make you pull your hair out.
