Sometimes it happens that even good trousers become short. This happens after washing. The missing 4–5 cm can be returned, and no one will notice the repair. This problem also affects rapidly growing children and adolescents.
Usually on trousers there are a few centimeters left for hemming. We will use them, and, of course, we need to add other fabric.
Method one
It is not necessary to have exactly the same material; other fabrics will work.
First you need to open the side seams by 5–6 cm.
Then prepare strips of fabric or braid, their length should be the same as the width of the halves of the trousers. In height they will be slightly larger than the lapel of the trousers, about 5 cm.
Sew the stripes to the trousers, iron the seams, trim the edges.
Sew the seams to the end of the legs.
Sew side seams.
Fold up the bottom where the stripes are sewn and tuck the edge at the level of the fold that was originally on the short trousers.
Stitch.
Method two
The finished product will be a cuff, so you need to select a fabric that matches the tone or is exactly the same. This addition will look very neat.
Open the side seams and remove the overstitching. Prepare strips of fabric 10 cm wide.
Sew them to the trousers. Trim the edges and immediately overcast on three sides.
Sew side seams. Direct the cuff seams towards the trousers.
Fold the sewn part to the original fold and stitch.
Turn the cuffs up to the stitching.
Sew the cuffs to the side seams.
It is important to iron the seams after each line, so everything will look good.
In both cases, the trousers will become 4–5 cm longer. This will be enough for them to become as before.
There are other ways to lengthen. For example, sew a folded cuff to the edge of the legs or, if these are jeans, sew lace.
