In this tutorial, we learn how to use a zigzag stitch as an overlocking stitch. First, put your fabric under the sewing machine and place the edge close to the needle. Sew the side of the fabric and when you are done, you will have the overlocking stitch. This will stop your edge from being raw and there won't be any frays on the side, which will reduce unraveling. This is very easy to do and just takes a few minutes. Make sure you prepare your fabric before you do this stitch and you will be prepared in no time!
