How to Sew a Straight Seam

You can learn to confidently and accurately sew a straight seam.

You will need

  • Straight pins
  • A measuring tape
  • A sewing machine
  • Masking tape

Step 1 Align the fabric to be hemmed and pin it in place. Align any notches, dots, or other pattern markings when pinning the pieces together.

Step 2 To determine seam allowance, measure the distance on the needle plate from the needle to the right of the presser foot. Mark the distance with a piece of masking tape on the needle plate.

Step 3 Put the fabric under the presser foot and line up the edge with the masking tape seam guide.

Step 4 Lower the presser foot and check that the fabric has not shifted.

Step 5 Sew the fabric together, keeping the fabric lined up with the seam guide. Remove pins when they are two inches from the presser foot.
