Measure the shortening, fold half of it as a tuck, and sew just above the original hem — the factory edge is then simply moved upwards. The faded, worn hem that identifies good jeans stays intact.
The method.
One. Try the jeans on and mark how much shorter they should be. Call that amount X.
Two. Turn the leg so the original hem is on the outside, and fold the fabric up to form a tuck. The fold must be half of X from the bottom, because a tuck removes twice its depth.
Three. Pin the tuck, keeping the original hem stitching perfectly parallel to the folded edge all the way round. This is the step that decides whether the finished hem is level.
Four. Sew just above the original hem stitching — 1 to 2 mm above it, on the tuck side, so the new stitching sits hidden right against the old.
Five. Trim the tuck down to about 6 mm, finish the raw edge with an overlocker or zigzag, and press the remaining allowance upwards.
Practical points. Use a jeans needle, 100/16 or 110/18, and a stitch length of 3 mm. Sew slowly over the side seams, which are the thickest points, and turn the handwheel by hand there. Level the presser foot with a folded scrap as you climb the seam.
Match the thread to the original topstitching if any new stitching will show — usually gold or orange.
Try them on before trimming the tuck. Once cut, it cannot be undone.
Questions people actually ask
How much can I take up this way?
Comfortably up to about 5 cm. Beyond that the tuck sits high on the leg and starts to show, and a conventional hem is better.
My hem came out uneven.
The tuck was not parallel to the original hem all the way round. Pin against the existing hem stitching rather than measuring from the floor.
