What Do You Need For Hemming?

You will first need a dependable and competent sewing machine to hem your jeans with a sewing machine. If your sewing machine can handle denim, that is an added advantage. Ensure your sewing machine has a denim needle (size 90/14 is recommended) for smooth and efficient performance on jeans fabric.

Select a matching sewing thread for your jeans. It is advisable to use a polyester thread, which is solid and durable. You will also need a bobbin filled with the same thread to ensure consistency in your stitching.

Precision is vital when hemming jeans. Use a measuring tape or a ruler and a fabric marker or chalk to mark the desired length accurately. A seam gauge can also help measure and maintain a consistent hemming distance.

A pair of sharp scissors is a must for cutting the excess fabric. Always opt for a high-quality pair to ensure clean and precise cuts. Have a set of straight pins to hold the fabric in place while sewing. These pins will help you maintain the desired length during the sewing process.

An iron is handy for pressing the newly created hem, giving it a professional, polished appearance. Though not a strict requirement, a height compensation tool can be beneficial when sewing thick seams as it ensures even pressure and fabric feeding under the foot.

For sewing machines with specialized presser feet, consider using the jeans foot #8. This foot is designed explicitly for handling thick fabrics and can make it easier to sew denim.

If you own a serger, it can be employed to finish the raw edges of the hem. This prevents fraying and contributes to durability. Although this step is optional, it adds a refined touch to your finished hem.

How To Choose The Right Thread And Needle?

When hemming jeans with a sewing machine, selecting the appropriate thread and needle is crucial to ensure a strong, neat, and durable finish.

Firstly, working on the thread. The ideal sewing thread for jeans is a strong, high-quality one that can withstand the wear and tear that jeans typically endure.

A jeans thread will provide the best results, but a heavy-duty polyester or durable cotton thread can also suffice if unavailable. Remember that the thread should match the color of your jeans to maintain a consistent appearance.

Now, moving on to needles. Sewing denim, especially heavy denim, can be a bit challenging. For this task, you’ll need denim needles specifically designed for sewing machines.

These needles are more robust and have a sharper point, allowing them to penetrate the dense fabric without breaking or causing skipped stitches.

To make hemming your jeans even more accessible, follow these tips:

  • Use a fresh denim needle for each project to ensure optimal sewing performance.
  • Test-stitch a scrap piece of denim beforehand to confirm that your sewing machine’s tension and stitch length settings are suitable for the fabric.
  • Since denim can be thick, especially at the seams, use a sewing machine with a solid motor to handle this heavy-duty task.

How To Mark And Measure For Hemming?

To achieve the perfect hem, start by measuring and marking the desired length on your jeans. Follow these simple steps to ensure accurate measurements and precise markings:

  • Put on the jeans along with the shoes you are most likely to wear them with. This helps determine the ideal length based on your shoes’ heel height.
  • Use pins or a fabric marker to mark the new hem length on each pant leg. Place the pins or make markings evenly around the entire leg opening to create a consistent length.
  • Remove once the jeans are marked, and lay them flat on a clean surface. Use a ruler or measuring tape to double-check the distance between the pinned or marked line and the original hem.
  • Calculate the hem allowance by adding an extra ½ to 1 inch (1.3 to 2.5 cm) to your desired length. This extra fabric allows for folding and securing the new hem in place.
  • Mark the hem allowance line along the leg opening using your ruler or measuring tape. It’s essential to be consistent with this measurement to ensure a neat, even finish after sewing.
  • Trim excess fabric if necessary, cutting along the hem allowance line with sharp scissors.
  • Press the hem before stitching to make sewing easier. An iron folds and presses along the desired length line, creating a crease. Then, fold the fabric once more along the hem allowance line and press it again to create a double-folded hem.

Step-By-Step Hemming Process

First, you should gather your materials. You will need a sewing machine, thread, fabric scissors, straight pins, a sewing machine needle, a free arm, and a pressing tool.

Start by putting on your jeans and folding the hem to the desired length. Use straight pins to temporarily secure the new hem, ensuring it’s even all around. Remove your jeans, and measure the hem allowance. This is the extra fabric you will fold to create the hem.

Next, press the hem using a pressing tool. This property sets the fold and makes the jeans easier to sew. Make sure to press the fold smoothly so there are no wrinkles.

After pressing the hem, pin the folded hem in place. Space the straight pins about 1-2 inches apart, parallel to the raw edge. This helps keep the hem evenly and firmly aligned while sewing.

Now, it’s time to set up your sewing machine. Choose a thread that matches your jeans and thread the needle and bobbin. Use a jeans needle designed explicitly for sewing through thick and heavy fabrics like denim.

Place the jeans under the sewing machine’s presser foot, with the folded hem facing up. Utilize your sewing machine’s free arm feature, making sewing circular hems easier.

Begin sewing along the hem allowance, using a straight stitch. Sew as close to the raw edge as possible to prevent fraying. If your machine has a zigzag stitch option, sew the raw edges and provide a clean finish.

Continue sewing around the entire circumference of the jeans leg, making sure to backstitch when you begin and end your stitching. This ensures that the thread doesn’t unravel and your hem stays intact.

Once you have sewn the hem, carefully trim any excess fabric with your fabric scissors, leaving about 1/8-inch of fabric beyond the stitch line to prevent fraying.

Finally, give your jeans a good press once more to set the stitches and smooth out any wrinkles in the hem. Your jeans now have a professionally hemmed finish, and you can confidently wear them at your preferred length.

Special Techniques For Jeans And Denim

  • First, prepare your jeans by marking the desired length with a straight stitch. Cut off any excess fabric with your fabric scissors, leaving about an inch for the final hem. To maintain the original hem, fold the bottom edge of the jeans up to the desired measurement, ensuring the side seams are aligned. Press this fold well for easier stitching.
  • Instead of using a standard straight stitch, opt for a triple straight stitch for added strength and durability on your jeans. This stitch will secure the hem and prevent fraying of the raw edges. Additionally, use a denim needle designed to pierce through thick fabrics like denim without breaking.
  • Topstitching is a critical technique when hemming jeans; it adds strength and matches the original seams. When topstitching, make sure to use a jeans thread that closely matches the color of your jeans. Begin stitching at the inseam, using jeans foot #8 to handle the thick fabric better.
  • While sewing the side seams, you may encounter some challenges due to the thickness of the fabric. To tackle this issue, use a height compensation tool or a makeshift tool like a folded piece of fabric. Place this tool under the presser foot to balance and level the sewing machine, allowing it to glide smoothly over the side seams.
  • When you reach the end of the hem, backstitch for about one inch to secure the stitching. This will prevent the thread from unraveling and ensure a durable finish for your DIY jean hemming project.
