Using the piece I cut in class 32, I sewed a 8mm bias channel about 30mm from the selvage edge. This was to put in elastic so the edge would be ruffled. I then gathered along the curved edge so that it would provide the baggy shape with a straight edge at the bottom of the cuff.
The cuff had to fit in to the bodice sleeve, so gathering had to fit on a bias strip 36cm long.
The elastic channel looked really bulky and not very good.
Because it looked so hideous, on the other cuff, I just put a pleat in the fabric and threaded the elastic through that. The elastic I was using was flat and only 4mm wide.
This looked a lot better, so I unpicked the other cuff and did it the same way. All of this had to be hand sewn as it is very visible and machine stitching would not be correct for this period.
Once I was happy with the cuffs, I just slip stitched them to the facing inside the sleeve.
