Getting Started: Fabric and Notions for Making a Pair of Trousers
Before you start sewing, make sure you have everything ready. You’ll need:
- A sewing machine to sew
- Sharp fabric scissors
- Measuring tape to measure your waist and waist and hip
- Pins or clips
- An iron
- Thread that matches your fabric
- A sewing pattern for basic trousers
- A piece of elastic if you’re making trousers with an elastic waistband
- Your chosen fabric and notions
Pick a soft cotton or jersey fabric if you want to sew comfortable trousers. This kind of fabric for your trousers is great for beginners and easy to work with.
Cutting the Trousers Pieces: Using a Sewing Pattern for Your First Pair of Trousers
Start by cutting your fabric. Carefully cut out the pattern and then cut out the fabric along the outlines. Make sure you label each piece—like the front, back piece, and waistband.
When laying out your trouser pieces, remember to keep the right sides together. This means the side of the fabric that will show when worn should face inward while sewing. The wrong side of the fabric should face out.
Make sure to cut one of your trouser legs facing left and the other facing right. That way, you’ll end up with a proper front and back leg.
Sewing the Side Seams and Trouser Legs: How to Sew Trousers Step by Step
This is the fun part—sewing the pieces together to make a full pair of trousers.
Step 1: Sew the Side Seams
Take the front and back piece of each leg and pin and sew the outer side seam. Use a straight stitch with your sewing machine to secure the edge.
Step 2: Sew the Inseams
Next, pin together the inside seams of the legs—these run from the crotch to the ankle. Sew a straight stitch along this line. Now your legs together should start to look like trousers.
Step 3: Sew the Crotch Seam
Turn one of the pant legs right side out. Slide it inside the other leg so that the right sides are touching. You’ll be matching the crotch curves. Now sew the crotch seam carefully, starting at the back of the trousers and going to the front. This is an important seam, so go slow and steady.
Many sewing tutorials suggest sewing this part twice for extra strength. You can also sew along the edge with a zigzag stitch to prevent fraying.
Step 4: Turn the Trousers Inside Out
Once you’ve finished the crotch seam, gently turn the trousers inside out so both legs are facing the right way. Your trousers right side should now be visible, and you’ll start to see a real shape forming.
Step 5: Create the Waistband
Take the waistband piece and fold it in half lengthwise, with the wrong side facing in. Pin and sew it to the top of the trousers, leaving a small opening at the back.
Cut a piece of elastic that matches your waist size. Insert a safety pin on one end of the elastic and feed the elastic through the waistband. Make sure the elastic doesn’t twist as it goes in and comes out the other side.
Once both ends of the elastic together meet, sew the opening closed. This is how you finish trousers with an elastic waistband.
Step 6: Hem the Bottom of the Leg
Fold the bottom of the leg up twice to hide the raw edge. Pin and sew it using a straight stitch. Repeat this on both legs. Make sure they’re even so your trousers won’t look lopsided.
Joining the Crotch Seam: A Simple Step to Make a Pair of Trousers
Press all seams flat with your iron. This gives your trousers a neat, clean finish. Clip any loose threads.
If this was your first pair of trousers, take a moment to admire your work! You now know how to sew a pair of trousers from start to finish.
If you want to go further, you can add details like pockets, topstitching, or even a fly front zipper.
Troubleshooting and Tips
Here are some things to keep in mind as you improve your trouser sewing skills:
- Always cut out the pattern accurately to avoid uneven legs.
- Match front and back leg pieces carefully before you sew the two together.
- If your trousersfeel tight, check your waist and hip measurements again.
- It’s easier to sew when you iron each seam as you go.
- If you’re not ready for full-length trousers, try making a pair of shorts first.
- If the elastic slips while threading, cut a piece of elastic a bit longer next time.
