Attaching a Sleeve

There are a few techniques when it comes to attaching a sleeve. Here's a basic technique to start you off

1. Cut out sleeves and front/back pieces.
2. Sew shoulder seams together, press and overlock.
3. Lay front and back piece flat, right side up.
4. Pin sleeve at shoulder point of front and back, matching the notches, right side to right side (if the sleeve overlaps there is too much ease and you will need to use a 5mm gathering stitch to fit ease into armhole)
5. From the shoulder point, pin all the way to one side seam, matching the notches as you go.
6. Repeat for other side.
7. Stitch with a 1cm seam allowance from side seam to side seam.
8. Press the seam towards the sleeve and overlock
9. Overlock the hem of the sleeve, turn up 1.5 cm and press (wrong side to wrong side).
11. Stitch 1.5 cm hem.
12. Fold sleeve right side to right side, matching the sleeve hem, under arm, and side seams to hem of shirt front/back.
13. Stitch 1 cm seam allowance.
14. Press open (for a nice finish) and then press to one side, overlock (seams are generally pressed towards the center back).
