Answer 2:
A basting stitch is the simplest stitch you can make. You push the threaded needle through the layers of fabric, and bring it up about 1/2 inch away. It works best when you keep the stitches as straight and even as you can. Since it is a temporary stitch, it doesn't have to be perfect. The reason for the basting stitch is to hold the pieces together until you finish sewing or working with the project.
