Inspect the fold
Open the cuff if possible and check both the outer surface and the turn. The visible hole may be smaller than the weakness along the fold or seam.
Keep buttons, buttonholes and fastenings clear. Mark a patch that reaches stable cloth but does not interfere with the cuff’s opening.
Reduce bulk
Choose a patch that sits smoothly across the worn area and a thread weight that can pass through the folded layers. If the edge is thick, a shorter needle and slower rhythm may help.
Use an open or directional pattern that follows the cuff rather than packing the turn with dense crossings. The cuff must still fold without a hard ridge.
Secure the high-wear edge
Finish the patch edge with even stitches and inspect the reverse for loops that can catch on a sleeve. A neat edge is part of the repair’s durability.
Wash and fold the cuff as it will be used, then check whether the patch has shifted. Adjust the edge before the garment returns to regular wear.
