Open-backed pants look like pants with torn crotch. Sewing them is as simple as sewing clothes that are usually broken. Prepare needles, thread and scissors. First, turn the open-backed pants upside down, align the positions of the open-backed pants together, and then start sewing with needles. You can choose to stay away from the crotch at the starting position and sew the stitches as small as possible, which will look more beautiful and detailed. At the same time, you should choose lines similar to the color of your pants, and you can't use some lines with more prominent colors, otherwise it will be more obvious.
After sewing, turn your pants over. If it is uneven, you can iron it with an iron, so that the style of pants is almost the same as that of ordinary pants. In addition, if you don't know how to sew, you can also refer to the sewing method in the video below to sew open back pants.
