Set-in sleeves vs. Flat
A flat sleeve is sewn with side seams are closed and before the body piece is sewn, it is an easy and accurate method. In contrast, set-in sleeves are inserting and sewing the sleeves once the body piece is done.
A set-in sleeve is a classic sleeve where the seam is all around or in the round of the arm opening. It fits various sleeve shapes and lengths.
Set in sleeves can be flat, puffed, fabric overlaps, butterfly sleeve, and smooth. The sleeve can be short, capped, bracelet length, ¾ length, elbow length, full length, or bracelet length.
A flat sleeve is where seams are press at the garment backside to get a C-shaped sleeve that creates a neat and flat finish.
Sewing Sleeves Flat
The sewing sleeves flat method works well and is a faster process for knits instead of woven fabric. This method is employed when the garment is still in pieces that have not been sewn, or the body piece isn’t ready yet.

Follow the steps to sew sleeves flat:
- Close the shoulder seams and overlock stitch to finish. Line up the right sides of the body piece for the seams to be even. Pin the edges for securing and then sew along with a straight stitch to around 1.3 cm or ½” from the raw fabric edges.
- Don’t go beyond the shoulder regions and don’t sew along the armhole openings or neckline for a properly functioning garment.
- Leave the body piece sides open. Fold in half and mark the center to locate the sleeve center and shoulder center for even fit for both.
- Match the sleeve and armhole opening edges, and open the garment with the right fabric side facing up.
- Take one sleeve and turn to the right side, but facing down on the garment/body piece, and line the shoulder part of the body piece and sleeve.
- Pin the sleeve to armhole opening to secure. Pin from the shoulder center and go around with the sleeve for even distribution.
- Sew a straight stitch along the fabric’s raw edges about 1.3cm or ½” off the edge. Remove the pins and cut the extra threads once complete.
- Repeat the above steps for the second sleeve leaving the sleeve sides and garment sides open.
- Turn the body piece inside out and the edges of sleeves and garment should be lined up.
- Pin the sides and sew straight stitch along the sides and 1.3 cm or ½” off the fabric edges.
- Cut the extra threads once the sleeves are finished.
How to sew a set-in sleeve
The set-in sleeve is generally used for any woven garment such as cotton or linen. This method of sewing sleeves is used for ready or sewn body pieces.
Most set-in sleeves consist with sleeve cap ease where the measurement of the sleeve cap is slightly bigger than the armhole. Women’s fitted shirts have an armhole seam that sits further in from the shoulder, so the ease prevents a fit issue.
Follow the steps to sew set-in sleeves:
- Turn the garment inside out. If the sleeves are sewn at the bottom edge then you just need to line up and sew along as mentioned above.
- If not, after turning inside out, your sleeves should be slipped to the right side out through the armhole opening. Edges of the shoulder area and armhole opening should be aligned.
- Locate the seam on the bottom edge and secure by pinning the seams together. Pin around the sleeve by linking the armhole opening and sleeve. Distribute fabric evenly while pinning with raw edges facing one another.
