Setting in Sleeves

Step-by-Step Instructions:
Follow these steps and your set‑in sleeves will appear smooth, secure, and comfortable—hallmarks of expert garment construction.
Materials Needed:
- Garment bodice with armholes assembled and pressed
- Sleeve pieces with notches, shoulder dot, and easing stitches sewn
- Matching all‑purpose thread
- Sewing machine with universal needle (size 80/12 for wovens, ballpoint for knits)
- Pins or fabric clips
- Tailor’s ham or rolled towel for pressing curves
- Pressing cloth and steam iron
Tips Before You Begin:
- Mark all notches, shoulder dots, and front/back indications clearly before sewing.
- Run two rows of long machine basting stitches (ease stitching) between front and back notches ⅛ in apart within seam allowance.
- Gently pull bobbin threads to form subtle gathers—just enough to shrink excess cap ease, not create visible puckers.
- Press sleeve cap over a ham with steam before insertion to pre‑shape the curve.
- Insert sleeves with garment body turned inside out and sleeve right side out—“right sides together” is easiest this way.
1. Prepare the Sleeve Cap
- Sew two parallel basting rows along the sleeve cap between notches at ⅝ in and ½ in seam allowances.
- Leave thread tails long so they can be pulled to ease fullness.
- Press the sleeve cap against a ham using steam to set a gentle curve.
2. Match Underarm Seams
- Turn the garment inside out.
- Keep the sleeve right side out.
- Insert the sleeve into the armhole, matching underarm seams first and pinning securely.
3. Align Notches and Shoulder Dot
- Match front and back sleeve notches to corresponding bodice notches.
- Pin the shoulder dot to the shoulder seam.
- Distribute pins evenly around the armhole, leaving the cap ease area unpinned for adjustment.
4. Ease the Sleeve Cap
- Pull the bobbin threads of the basting rows to gather excess cap ease until the sleeve fits smoothly into the armhole.
- Evenly spread the fullness between front and back notches, avoiding concentrated puckers.
- Pin every ¾ in along the eased section, with pins perpendicular to seam allowance.
5. Stitch the Sleeve Seam
- Stitch around the armhole with a ⅝ in seam allowance, sewing sleeve side up for better control of cap ease.
- Sew slowly, removing pins just before the needle reaches them, smoothing fabric as you go.
- Backstitch at start and end for security.
6. Check and Trim
- Turn garment right side out and inspect sleeve cap for tucks or puckers; pick out and restitch small sections if needed.
- Trim seam allowance to ⅜ in; clip curves lightly and notch the deepest sections to reduce bulk.
7. Finish and Press
- Finish seam allowances together with a serger or zigzag, or individually press open if fabric permits.
- Press seam toward the sleeve using a ham to maintain the cap’s rounded shape.
- Steam for final shaping, then allow to cool on the ham for a crisp, professional sleeve head.
