Choosing the Right Denim Fabric

To make pants, you should start by choosing the right denim fabric for your project. There are different types of denim fabric available, each with its own unique characteristics. The most common types include raw denim, stretch denim, and washed denim.

Raw denim is known for its stiffness and durability. It has not been washed or treated, giving it a dark and rigid appearance. This type of denim requires a special care routine, as it should not be washed frequently to maintain its quality.

Stretch denim, as the name suggests, has a certain amount of elasticity. It is a popular choice for pants as it offers comfort and flexibility. This type of denim is great for fitted styles and is usually machine washable.

Washed denim has been treated to achieve a faded or distressed look. It comes in various washes, from light to dark, and can give your pants a more casual and worn-in feel. This type of denim can be machine washed, but it’s important to follow the care instructions to prevent color fading.

When choosing denim fabric for your pants, consider the desired style, comfort, and care routine. Understanding the different types and their washing and caring requirements will help you make the right choice for your project.

Taking Accurate Body Measurements

First, you’ll need to ensure that you take accurate body measurements before starting your project. Taking body measurements accurately is crucial for creating well-fitting pants. To get started, grab a measuring tape and follow these steps.

Begin by measuring your waist, which is the narrowest part of your torso. Wrap the tape around this area, making sure it’s snug but not too tight.

Next, measure your hips by placing the tape around the widest part of your buttocks. Be sure to stand up straight and avoid pulling the tape too tight.

Another important measurement is the inseam, which is the distance from your crotch to the desired length of your pants. For this, stand with your feet shoulder-width apart and measure from the crotch to just below your ankle bone.

Common mistakes while measuring the body include not measuring at the right spots, pulling the tape too tight, or not standing up straight. Taking accurate body measurements will ensure that your pants fit perfectly and are comfortable to wear. So, take your time and double-check your measurements before cutting into your denim fabric.

Preparing the Pattern for Pants

When preparing the pattern for pants, there are three key points to consider: choosing the right measurements, tracing the pattern, and adjusting for seam allowances.

Start by taking accurate body measurements to ensure a perfect fit. Then, transfer those measurements onto the pattern, making sure to trace all the necessary lines and markings.

Choosing the Right Measurements

Before you start cutting the denim fabric, make sure you have the right measurements for your pants. Proper fitting techniques and understanding body proportions are crucial in achieving a well-fitting pair of pants.

To begin, measure your waist, hips, and inseam accurately. Use a flexible measuring tape and keep it snug against your body, but not too tight.

For the waist measurement, wrap the tape around the narrowest part of your torso, usually above the belly button.

For the hip measurement, measure the fullest part of your hips.

The inseam measurement is the distance from your crotch to the desired length of your pants. Remember to account for any desired ease or adjustments when taking these measurements.

Taking accurate measurements will ensure that your pants fit comfortably and flatter your body shape.

Tracing the Pattern

To trace the pattern onto the paper, align the edges of the pattern with the edges of the paper and secure them in place with weights or pins. This step is crucial in ensuring accurate and precise pattern alterations for your pants.

Tracing techniques allow you to transfer the original pattern onto a new piece of paper, which can then be modified to fit your desired measurements. Take your time to carefully trace each section of the pattern, making sure to capture all the necessary details. You can use a pencil or a tracing wheel to create the lines on the paper.

Once the pattern is traced, you can proceed to make any necessary alterations to achieve the perfect fit for your denim pants.

Adjusting for Seam Allowances

Now that you’ve successfully traced your pattern onto the denim fabric, it’s time to adjust for seam allowances. Seam allowances are the extra fabric you need to leave around the edges of your pattern pieces to allow for sewing. They ensure that your finished garment fits well and doesn’t end up too small.

Here are some seam allowance techniques to keep in mind:

  • Use a seam gauge to measure and mark the correct seam allowance on your fabric. Place the edge of the gauge along the edge of the fabric and use the slider to set the desired seam allowance. Mark the seam allowance with a fabric marker or chalk.

Troubleshooting common sewing mistakes:

  • If your seam allowances are too narrow, your garment may end up too tight.
  • If your seam allowances are too wide, your garment may end up too loose or bulky.

Cutting and Marking the Denim Fabric

First, grab your denim fabric and use chalk to mark the measurements for cutting the pants.

To ensure accurate and precise cuts, it’s important to use proper cutting techniques. Lay out your denim fabric on a flat surface, ensuring there are no wrinkles or folds.

Take your measurements and use fabric markers or chalk to mark the cutting lines on the fabric. It’s important to be careful and precise while marking the fabric, as any mistakes can affect the fit of the final garment.

Once you have marked the measurements, use a sharp pair of fabric scissors to cut along the lines. Take your time and cut slowly to ensure clean and even edges.

Remember to leave extra fabric for seam allowances, which will be used for sewing the pants together. By following these cutting techniques and using fabric markers, you can confidently cut your denim fabric and move on to the next step of making your own pants.

Sewing the Front and Back Panels

Ensure that the front and back panels are aligned properly before sewing them together. This is a crucial step in creating a well-fitting pair of pants. Here are some tips to help you sew the front and back panels seamlessly:

  • Pant Styles:

  • Straight leg: This classic style is timeless and flattering for all body types. It gives a clean and streamlined look.

  • Bootcut: This style is fitted through the thighs and gradually flares out from the knee, allowing you to wear boots comfortably.

  • Troubleshooting common sewing mistakes:

  • Uneven seams: To avoid this, make sure to pin the panels together accurately before sewing. Double-check the alignment by measuring the distance from the edge of the fabric to the seam on both sides.

  • Tangled threads: Keep the threads taut while sewing to prevent them from getting tangled in the machine. Trim excess thread after each seam to avoid any snags or knots.

Adding Pockets and Belt Loops

To add pockets and belt loops, start by folding and pressing the fabric to create clean edges. This will ensure that your embellishments look professional and polished. Once you have prepared your fabric, you can move on to adding the pockets and belt loops.

When adding pockets, you have a few options to choose from. You can either sew on patch pockets or create inset pockets. Patch pockets are great for a more casual look, while inset pockets are perfect for a sleek, tailored finish. The table below outlines the steps for adding each type of pocket:

Patch Pockets Inset Pockets
Cut out pocket pieces according to desired size Mark pocket placement on front panel
Press under ¼ inch on all sides of pocket pieces Cut out pocket opening on front panel
Pin and stitch pocket pieces onto desired location Pin and stitch pocket bags to opening
Reinforce corners for durability Sew pocket bags to front panel
Finished pocket should lay flat and be securely attached Trim excess fabric and press pocket edges

Adding belt loops is a simple process. Cut out fabric strips, fold them in half lengthwise, and press them. Then, stitch the folded strip onto the waistband, evenly spacing them apart. Ensure that the belt loops are securely attached by reinforcing the stitching at the ends.

Troubleshooting common issues when adding pockets and belt loops include ensuring that the measurements are accurate, using the right needle and thread for denim fabric, and taking your time to sew carefully. By following these steps and troubleshooting tips, you’ll be able to add pockets and belt loops to your pants with ease.

Constructing the Waistband and Fly

When constructing the waistband and fly, you’ll need to carefully align and stitch the fabric pieces together. This is a crucial step in making pants as it ensures a proper fit and a functional closure.

Here are some tips to help you navigate this process smoothly:

  • Troubleshooting fitting issues:

  • If the waistband feels too tight, you can add a small extension piece to the back waistband to give it some extra room.

  • If the waistband is too loose, you can take it in by making a few small darts along the top edge.

  • Adding decorative stitching details:

  • Once the waistband and fly are securely attached, you can add some decorative stitching to enhance the overall look of your pants. Consider using contrasting thread or a decorative stitch pattern to create interesting details.

  • You can also experiment with different topstitching techniques to add visual interest to the waistband and fly area. Try using a double-needle or a decorative stitch to create unique designs.

Hemming and Finishing the Pants

Once you’ve completed the main construction of your pants, it’s time to focus on hemming and finishing the edges for a polished look.

To start, press and iron the hem to create a clean finish. This step is crucial in achieving a professional-looking result. By pressing the fabric, you’ll ensure that the hem lays flat and stays in place.

Next, you can choose from different stitching techniques to hem and finish the pants. One common method is using a straight stitch along the edge of the fabric. This creates a simple and clean finish. Alternatively, you can opt for a blind hem stitch, which hides the stitching on the outside of the garment for a more seamless look.

Additionally, you may want to consider adding a decorative touch to your pants by using a contrasting thread color or adding decorative stitches along the hemline. This can elevate the overall appearance of the garment and make it unique to your personal style.


To conclude, making pants using denim fabric is a straightforward process that can be accomplished with some basic sewing skills. By choosing the right denim fabric, taking accurate body measurements, and following the steps of preparing the pattern, cutting and marking the fabric, sewing the panels, adding pockets and belt loops, constructing the waistband and fly, and finally, hemming and finishing the pants, you can create your own stylish and comfortable pair of denim pants.

So why not give it a try and enjoy the satisfaction of wearing something you’ve made yourself?
