It's a simple way to keep your private life out of the public eye.The idea is to sew an extra flap inside your jeans to keep them from falling outside.
Step 1: A sewing machine is needed.
It can be sewn by hand, but a machine makes it simpler.
Step 2: Obtain the fabric for the flap.
Step 3: Measure your length.
This measurement is called "A".
Step 4: When you unbutton the top button of your jeans, you need to measure the distance.
This measurement should be called "B".
Step 5: Cut two pieces of fabric equal to A times B and an extra inch in each direction.
You can see the sketch.
Step 6: The fabric needs to be sewed together with the right sides facing.
Leave at least two inches for turning.
Step 7: It's easy to clip the corners.
Step 8: Press the edges carefully when turning right side out.
Step 9: To tuck the open edge inside, topstitch the edges.
Step 10: There are two button holes on the flap.
There are two holes, one near the top and one below the pocket opening.If you want to hide the fact that you have buttons on your pants, these are the places to go.
Step 11: Take the long edge of the flap and sew it to the inside of your former zip up.
You can see the sketch.
Step 12: After the flap is sewn into the pants, mark the location of the button holes.
Step 13: Use two buttons to sew.
Step 14: Voila!
You now have three places where you can go without a broken or broken sipper.
