Remember that the paper pattern represents finished size, so I cut the material 1/2 inch outside the edge of pattern.


Then I pressed that 1/2 inch under, to finish the raw edges of the cuff.


The existing sleeves have a small vent, which I stitched closed to prevent it bunching up underneath the applied cuff.


Pinned the cuff to the sleeve, first along the hem (with new cuff hem about 1/8 inch below the existing sleeve hem).


Then pinned the upper edges of the cuff to the sleeve.
