There are two variants for cuff processing. The first variant is the simpler one, in which you stitch the cuff all the way around the edge. But if you don't want any quilting on your cuffs and you're a sewing professional, then dare to try the second variant.
Variant 2: Sew the raw edge of the outer cuff to the prepared sleeve. Sew up to the notch of the understep. The upper photos are for orientation of the right arm, a cuff can always be tightened and opened backwards. Fold the marked corners on the photo together, against the break, right sides together. To topstitch the corners, slide the fabric away from the sleeve so you don't accidentally sew the sleeve on.
Topstitch the corners of the top and bottom step. For curves and corners, seam allowances are shortened with scissors and cut or cut off. The corners do not become too thick when turning and the seam allowances can be laid flat. It is particularly important that the seam is not cut. That's why we recommend that you sew just before the point and from there with a smaller stitch length. This guarantees you a corner that won't fray as quickly after trimming.
After turning, you should shape the corners with a corner and edge shaper and then iron them out.
Finally, you sew the hole on the inner cuff by stitching from the outside (right side of the fabric) in the shadow of the seam and rolling the seam allowance of the hole slightly outwards, it is best to pin this spot with extra needles. Or sew up the hole by hand, that's also an option.
Have lots of fun with it
