Sewing sleeves onto a body piece may seem like a difficult process, but it is much easier than you might think. There are 2 basic methods for attaching sleeves: sewing sleeves flat and sewing set-in sleeves. If your garment is still in pieces, then sewing your sleeves flat may be your best option. If your garment’s body piece and sleeves are already sewn up, then you would need to use the set-in sleeves option. After you finish sewing your sleeves, don’t forget to hem the ends!

Best Way to Sew Sleeves Flat

  1. Sew the shoulder seams closed, but leave the sides of your garment’s body piece open.
  2. Line up the sleeve’s shoulder end with the edge of the armhole opening. Pin them together.
  3. Sew a straight stitch about 0.5 inches from the raw edges. Repeat 1-3 on the other sleeve.
  4. Turn the garment inside out and pin the edges of the body piece and sleeves together.
  5. Sew along the bottom edge of the sleeve and along the sides of the garment’s body.

  1. The shoulder seams on your body piece need to be closed before you can sew a sleeve into place. Line up the correct sides of your body pieces so that the shoulder seams are even with each other. Then, pin the edges to secure them and sew along each of the pinned areas. Use your sewing machine to sew a straight stitch about 0.5 inches (1.3 cm) from the raw edges of the fabric.[1]
    • Do not sew past the shoulder areas. Avoid sewing along the neckline or along the armhole openings. Otherwise, your garment will not function properly.

    Before pinning and sewing your sleeve to the body piece, it is helpful to identify the central point of the shoulder. This will help to ensure an even fit between your sleeve and shoulder point. Fold your sleeve in half lengthwise and use a piece of chalk to mark the center point (the folded area) of the sleeve at the shoulder.[2]

    Open up your body piece so that the 2 pieces are spread out and the correct sides of the fabric pieces are facing up. Then, take 1 of your sleeves and turn it so that the correct side of the fabric is facing down towards the body piece. Line up the edges of the shoulder part of your sleeve with the shoulder of your body piece.[3]

    Pin along the edges of the sleeve’s shoulder area and armhole opening to secure them together. Make sure that the correct side of the sleeve’s fabric is facing the correct side of the body piece’s fabric. To ensure that the sleeve will be evenly distributed on the armhole opening, start pinning from the center of the shoulder. Identify the central point of your shoulder piece and pin this point to the shoulder seam on your body piece. Then, pin the rest of the sleeve to the armhole opening one side at a time.[4]

    The top part of the sleeve is usually the most complicated part to sew. Marking the center point will make things easier.
