Here’s how to add a sleeve to your corset: 

I used sleeve number two from Mood’s Valli Sleeve Pattern Pack for this hack! Download your sleeve pattern here.

Pattern pieces A, B, and C from the Spearmint Corset will be used

1. Reshape the edges of the straps: Straighten the rounded edges to create shoulder seams. Slightly extend the outer edge by 3/8″. This will prevent the sleeves from falling off the shoulders.
2. Trace the original armscye: Mood’s Ginger dress pattern was used to draft each sleeve of the Valli Sleeve Pack. On tracing paper, trace the armscye from the front and back of the Ginger Dress pattern. Align the traced armscyes on top of your corset pattern pieces. Start at the edge of the shoulder and try to match up the sides as close as you can.
3. Re-trace the new armscye: You may notice that your side seams may have slightly raised. Trace and blend the new side seam as close as you can. Both the front and back seams must match evenly to ensure the fit of the sleeve.
4. Transfer the sleeve notches: Since the Spearmint corset is a sleeveless pattern, we need to transfer the notches over from the Ginger dress pattern, keeping them in the exact location. Cut out your new pattern! Try a sample sleeve and make any adjustments if necessary.
