You can add extension patches to the waistline. It works well if you have high rise jeans. Choose between the stretch band and denim patches.

Though when using denim patches, make sure they have the same color as your jeans. In case the button doesn’t close, add an elastic extension at the end. It won’t require cutting of jeans, so less hassle on your part.

Method 1. Adding Extension Patches to Expand Jeans

Extension patches or panels are among the most popular methods for making jeans bigger. Add a piece at either the seam’s side or along the center back. They can give a new life to your old jeans while being fashionable and cute.

You can choose a fabric that compliments the color of your existing material for a more natural look. However, you can be as creative as you want by experimenting with different fabrics.

You will only need an extension panel or patches, pins, and your jeans in this project.

Step 1: Do proper measurements. Start by measuring around your waist, thighs, and hips. Besides, measure the distance between your body’s broadest area and your waistline. Lastly, measure the jeans’ waist. Make sure it is buttoned.

Step 2: You can create your own patch/panel or have a completely designed one.

Step 3: Cut the jeans carefully to the length of your patch or panel. Toss inside and out. Then, stitch from side to side together with the fabric’s inner seam in which the cut ends. Doing so will prevent the stitch from unraveling.

Step 4: Pin the patch or panel on your jeans. To avoid getting speared by the tiny sharps, pin with the right sides facing simultaneously.

Step 5: Next, sew the patch to your denim with an overcasting foot and stitch. Maintain 1/2 inch seam allowance. A serger machine is a nice-have but is not a dealbreaker if you don’t have one at home. Use a regular straight stitch instead if your machine is not capable of doing an overcasting stitch.

Step 6: Iron the seam. Toss the fabric right side out. After that, sew a straight stitch starting down to the sides of both patches. As for the top fold, hand stitch it so the patch will lay evenly in the jeans.

Method 2. Adding Extension at the Center Back of Your Jeans

Adding Extension at the Center Back of Your Jeans

Step 1: If your jeans have a center back belt loop, take it away using a seam ripper.

Step 2: Cut down the center back directly to the yolk with a sharp scissor. How far should you cut down depends if you need extra room in the hips.

Step 3: Cut and fold the piece of material. Again, pick a durable fabric in identical color or purchase a small patch. Fold in half. Make it twice the cut length.

Step 4: Grab your sewing pins and start pinning the fabric in the proper place.

Step 5: Create a zigzag stitch alongside the borders of your jeans. Do this by setting the machine to carry out a slackened stitch number and thick stitch width. You will need it to make a high-density stitch.

Step 6: Trim down extra fabric inside. Be careful not to cut into the spot you just stitched. You should leave at least 0.64 centimeter or 0.25 inches fabric alongside the border.

Method 3. Adding an Elastic Extension to Expand Jeans

What makes an elastic extension a better alternative is that it will shrink or grow with you. So, no more fitting issues!

Step 1: Choose an elastic with a similar width to the waistband of your jeans.

Step 2: Rip off the waistband with a seam ripper. You may want to mark your belt using a pin so you won’t have to rip it off completely.

Step 3: Cut down the marked waistband.

Step 4: Pin the elastic from the sides. It should go along the waistband’s front, too.

Step 5: Sew up while keeping a 1/4 seam allowance. Sew backward and forward multiple times as you can to strengthen the seam.

Step 6: It’s time to sew the other side of your elastic.

Step 7: Reconvene the waistband. Pin into position and then sew. The use of stretching and feed foot will help you achieve smooth sewing.

Step 8: Once the other side is completely sewn, enjoy your perfectly comfy jeans! That means you no longer have to hold your breath while wearing it.

Important Points to Note

Before doing any sewing projects with denim, it’s always recommended to prewash it. It will soften the fabric and make it a lot easier to manage it throughout the process.

When measuring your waist, divide the total amount in two mainly because you will add the piece of fabric to the jeans’ side seams. Assuming you need an extra two inches to your waistband. You must add two pieces of one-inch material for both seams.

You may notice the denim tends to stretch while sewing it. The trick here is to hold it securely both in the back and front of the needle. Be sure not to pull it, though! Still didn’t work? Don’t worry, as long as you have foot pressure or Teflon foot. Both will keep your fabric feed efficiently in the machine with little to no amount of friction.

Use thicker, sturdier pins when sewing denim items, such as jeans.

Step 1: Lay down the jeans on a table to start stretching the thighs of the pants.

Step 2: After this, use a spray bottle filled with water at room temperature to wet the pants. Wet the jeans from the knee to the bottom part of the pocket on both sides. 

Step 3: Put your foam roller or toilet paper roll into the pants leg for at least ten to fifteen minutes. Now, continue the same steps on the other leg. The amount of stretch you get to achieve will depend on the foam roller’s width.

Method 2: Wash Your Jeans And Wear Them In The Sun

Before moving on to a method that involves sewing, here’s another simple way out for you.

Step 1: Wash the pants on the cold setting of your washing machine or get them soaked in cold water for at least five minutes.

Method 3: Opening The Seam Between The Legs Of The Pants

You can open the seam between the legs (inseam) and alter the fit of the jeans around the thighs.

Is sewing not your thing but need to stretch your jeans for an upcoming event? There are other tricks for that, and I’ll share some of them below:

1. Spray lukewarm water on the waistband and its surrounding area. Don’t forget the back and front areas. They must be damp enough to stretch out the pant’s fibers. Then, stretch the waist using your bare hands. Pull towards the outside as hard as you can.

2. Put your pants on like you normally would and hop in the bath filled with water. Go down and sit for approximately fifteen minutes before getting out of the water. Bend your waist and enlarge your stomach to help stretch out the waistband.

3. Otherwise, toss your pants into the wash. Just don’t dry it. Take the fabric as soon as you complete the washing cycle. Tug the waistband over a piece of the wood, hook, or the back of a wide chair. You can use any materials providing they are able to stretch the pressure on your waistband.

4. If your jeans are made of 100% cotton (or at least close to it), consider washing it in hot water. Press hot iron to dry or allow to dry in the hottest setting.
