Use something straight - a book, cardboard, boxes or a simple ruler - to draw a line that is truly straight. This line will be your guide through the sewing process.
Some sewing machines have a seam guide engraved in the machine. It will help tremendously while sewing straight lines. If you don’t have a seam guide on your machine or it isn’t helpful for you, try using a headband, elastic or tape, to wrap around the arm of your sewing machine.
