lengthening the crotch in a pair of jeans

If your pants are long for your leg length (from the crotch point down) or if you are willing to make your pants a bit shorter you can do the following.

Since we don't know exactly how much we need to lengthen the crotch by, you can lower the crotch point by one and a half cm or about half an inch and sew from that point towards the front and back of the pants. Merging with the existing crotch seam line.

Then you need to remove the existing stitches of the inseams above the new crotch seam line, leaving about half a cm behind. Removing the stitches from the inseam will allow you to pull up the pants and test the new crotch length.

If you like to increase the crotch length some more, you can repeat the same process and lower the crotch point at the inseams by another cm. Then remove more of the stitches from the inseams to be able to pull your pants further up.

YOu can repeat this one cm at a time. Once you are satisfied with the crotch length, you need to trim away the excess fabric from the crotch seam allowances.

This process will shorten the length of your pants, by the amount that you lower the crotch point by.

Happy sewing,
