The goal of this tutorial is to teach you how to shorten blouse sleeves using elastic casings.
These casings create a ruffled effect:
If you’d rather create a ruffle-free sleeve, sew all around the sleeve after step 5.
Mark desired final length of sleeve on the underside (armpit) area of blouse. Feel free to measure a different shirt’s underside as a reference. In my case, the length was two inches.
Make another mark 0.5 inch (1.27 cm.) plus the width of your elastic below prior mark. It’s best to use elastic with a width between 0.25 and 0.5 inches (0.635 and 1.27 cm.) for sleeve casings.
Hold sleeve out and cut perpendicular to the grain.
Pin sleeve and trim so that edges are even.
Turn blouse wrong-side out. Along raw edges of sleeve, turn 0.25 inches (0.635 cm.) to the wrong side and press.
Fold along hemline so that raw edge is pressed against wrong side of garment. Sew close to raw edge fold, but leave space on each side of underarm seam so that elastic can be slipped through.
Sew all the way around the outer (hem) edge.
Thread elastic and pull all the way around sleeve. I used button thread tied to a needle, but it would be easier to thread it through with a safety pin.
Overlap elastic ends by 0.5 inch (2.27 cm.) and stitch them together with a crisscrossed square. Pull joined ends inside the casing. Edgestitch opening to close it, stretching elastic slightly as you sew.
