Mastering the art of hemming bootcut jeans is a skill that elevates your wardrobe from off-the-rack to perfectly tailored. It’s the difference between a sloppy, bunched-up look and a sleek, elongating silhouette. This guide is your comprehensive, no-nonsense roadmap to achieving that flawless finish at home. We’ll bypass the fluff and get straight to the practical, actionable steps, ensuring that every bootcut in your closet fits exactly as it should.
The beauty of a bootcut lies in its subtle flare, a design meant to drape over footwear. When the hem is too long, this effect is lost, replaced by a frumpy, wrinkled mess. A proper hem preserves the line, allowing the denim to fall gracefully and create a visually appealing, balanced proportion. This guide will walk you through the process, from the initial fitting to the final stitch, equipping you with the knowledge and confidence to tackle this essential alteration. We’ll cover everything from the basic tools you need to the advanced techniques that give your homemade hem a professional, store-bought quality.
The Essential Toolkit: Gathering Your Supplies
Before you even think about cutting fabric, you need to assemble the right tools. Having the correct equipment makes the job not only easier but also more precise, leading to a much better outcome. Don’t skimp on these; quality tools are an investment in your wardrobe.
- Sharp Fabric Shears: A dedicated pair of sewing shears is non-negotiable. Using them on paper will dull them instantly, making it impossible to get a clean, straight cut on denim. Look for a pair with a comfortable grip and a blade long enough to cut through multiple layers of fabric.
-
A Solid Straightedge or Ruler: A sturdy ruler is crucial for measuring and marking. A clear plastic quilting ruler is ideal because you can see the fabric through it, but any reliable straightedge will do.
-
Fabric Chalk or Disappearing Ink Pen: You need a way to mark your hemline that won’t permanently stain the fabric. Fabric chalk is a classic choice, while a disappearing ink pen is great for those who want to avoid chalk residue.
-
Good Quality Pins: Use sharp, fine pins that won’t snag the denim. These are essential for holding your hem in place before you sew.
-
An Iron and Ironing Board: Pressing is a critical step that many beginners skip. It sets your folds and creates crisp, professional-looking edges.
-
Sewing Machine: While hand-sewing is possible, a machine is required for a durable, professional-looking hem on denim. Ensure your machine is in good working order.
-
Denim Needles: This is a key detail. A standard universal needle will likely break or skip stitches on thick denim. Denim needles are stronger and have a sharper point designed to pierce tightly woven fabric.
-
Matching Thread: Choose a high-quality thread that matches the original color of the denim or the existing hem stitching. A polyester or cotton-wrapped polyester thread is ideal for durability.
The Golden Rule of Hemming: Measure Twice, Cut Once
This is the most critical stage. A mistake here is irreversible. Take your time and get this right. The goal is to determine the perfect length while the jeans are on your body, as a static measurement on a flat surface can be deceiving.
- Wear the Right Shoes: The fit of a bootcut is dependent on your footwear. Put on the shoes you’ll most often wear with these jeans. This is crucial for determining the correct length, as the hem should just skim the top of your shoe, or for a more classic look, lightly brush the floor behind the heel.
-
Stand Naturally and Straight: Stand up straight, with your shoulders back and feet flat on the floor. Don’t slouch or bend your knees. This provides the most accurate and natural position for marking.
-
Pin the New Hemline: While wearing the jeans and shoes, have a trusted friend, partner, or family member pin the new hem. They should fold the excess fabric inward, pinning the new hemline so the jeans fall at your desired length. Be very specific about where you want the hem to land. For a classic bootcut, the front of the hem should fall just above the top of your foot, while the back should be slightly longer, almost touching the floor.
-
Check for Consistency: Once the new hemline is pinned, check the length in a mirror. Walk around a bit to see how the fabric drapes. Make sure both legs are pinned to the same length. This is your final chance to make adjustments before you take the jeans off.
-
Mark the Pin Line: Take off the jeans carefully, keeping the pins in place. Lay them flat on a table. Using your ruler and fabric chalk, draw a clear, solid line at the pin line, all the way across the width of the leg. This is your new fold line.
The Art of the Original Hem: Preserving the Factory Look
Many people prefer to keep the original hem on their jeans. It’s a hallmark of quality and adds an authentic, worn-in look. This technique allows you to shorten the jeans while reattaching the original hem. It’s a bit more complex, but the result is well worth the effort.
- Measure and Mark: Using your ruler, measure from your new chalk line up the leg a distance equal to the original hem’s width, plus a half-inch seam allowance. For example, if your original hem is 3/4 inch wide, you would measure up 1.25 inches. Mark this new cut line all the way across the leg.
-
Cut the Excess Fabric: With your sharp fabric shears, carefully cut along the marked cut line. Be precise and steady. You now have the original hem as a separate piece of fabric.
-
Prepare the Hem Piece: Unpick the seam of the original hem carefully. You’ll be left with a strip of denim. Iron this strip flat to remove the creases.
-
Reattach the Hem: This is where it gets a little tricky. Turn your jeans inside out. Take the unpicked hem strip and align the raw edge of the strip with the raw edge of the jean leg, right sides together. The original stitch line of the hem strip should be facing outwards. Pin it all the way around, making sure the seams on the side of the jean leg and the hem strip are aligned.
-
Sewing the Seam: Using a denim needle and matching thread, sew a new seam with a 1/2-inch seam allowance. This seam will be just above the original hem’s top stitch line. Sew a straight, even line all the way around the leg.
-
Finishing the Hem: Press the seam allowance up, towards the jeans. Fold the hem strip over to the inside of the jean leg, so the original hem is now on the outside and the raw edge is tucked inside. The new stitch line will now be invisible from the outside.
-
Topstitch the Hem: Iron the folded hem flat. From the outside of the jeans, carefully topstitch along the original hem’s top stitch line. This will secure the new hem in place and mimic the original look. Use a sturdy thread for this final topstitch, as it will be visible. Sew a second topstitch if the original had a double stitch.
The Classic Hem: Simple and Effective
For those who want a straightforward, no-fuss hem, this method is perfect. It’s faster than the original hem technique but still results in a clean, professional finish.
- Mark and Measure: Just like before, wear the jeans with your desired shoes and pin the perfect length. Take them off and use your chalk to mark a clear line where the new hem will fold.
-
Measure the Hem Allowance: Measure down from your new fold line an additional 1.5 inches. This is your seam allowance. Mark a second line all the way across the leg.
-
Cut the Excess: Cut the excess fabric off along the bottom, second marked line.
-
Press and Fold: With the jeans turned inside out, fold the bottom raw edge up by 1/2 inch and press with a hot iron. This first fold will prevent the denim from fraying.
-
Second Fold and Press: Fold the hem up a second time, this time along your initial marked fold line. Press this second fold firmly. This tucks the raw edge inside the hem, creating a clean finish. Pin the hem in place all the way around the leg.
-
Sewing the Hem: Using a denim needle and thread that matches the denim, sew a straight stitch a quarter-inch from the top folded edge of the hem. Make sure to backstitch at the beginning and end of your seam to secure the stitches.
-
Finishing Touches: Trim any stray threads. Give the new hem a final press with the iron to set the stitches and create a sharp crease.
Advanced Techniques and Pro Tips
Once you’ve mastered the basics, consider these tips to elevate your hemming skills even further.
- Handling the Side Seam: The side seams on bootcut jeans are often thick, with multiple layers of fabric. Your sewing machine might struggle here. To help it along, use a “jean-a-ma-jig” or a similar tool. It’s a small plastic wedge that helps level the presser foot when crossing a thick seam. If you don’t have one, fold a small piece of scrap denim to the same thickness as the seam and place it behind the presser foot as you approach the seam.
-
The Power of Pressing: Don’t underestimate your iron. Pressing after every fold and every seam is what gives a homemade alteration a professional look. It makes the fabric lie flat and sets your creases, which is essential for accurate stitching.
-
Zigzagging the Raw Edge: For the classic hem, if you’re worried about fraying, you can run a zigzag stitch along the raw edge of the denim before you make your first fold. This is a quick and effective way to reinforce the edge and ensure durability.
-
Stitch Length: Use a slightly longer stitch length (around 3.0mm) for denim. A shorter stitch can make the fabric pucker and a longer stitch can look unprofessional. A longer stitch also helps the machine move more easily through thick fabric.
-
The Right Thread: Don’t just pick any thread. For a factory-like finish, look for a thick, topstitching thread that matches the color of the original stitches. It’s thicker and more durable, designed to be seen. You may need a special topstitching needle and to adjust your machine’s tension to accommodate the thicker thread.
Troubleshooting Common Hemming Issues
Even with the best preparation, things can go wrong. Here’s how to fix some common problems.
- Puckering or Wavy Seam: This usually happens when the fabric is being stretched while sewing. Make sure you’re not pulling the fabric through the machine. Let the feed dogs do the work. Also, check your thread tension. It may be too tight.
-
Skipped Stitches: The most likely culprit is a dull or incorrect needle. Change your needle to a fresh denim needle. If the problem persists, check that the needle is inserted correctly and that your machine is threaded properly.
-
Hem is Uneven: This is a measuring and marking issue. Go back to the beginning, re-pin the hem while wearing the jeans, and re-mark the line carefully. Consistency is key, especially when dealing with the subtle flare of a bootcut.
-
Stitches Break: You’re likely using a thread that isn’t strong enough for the job. Switch to a good quality polyester or cotton-wrapped polyester thread. If the issue is with the topstitching, upgrade to a specific topstitching thread.
The Final Step: The Perfect Fit
With your new hem complete, your bootcut jeans should now fit you like a glove. The hem should just graze the top of your shoes, with the back being slightly longer than the front. The subtle flare should be preserved, creating a clean, elongating line that complements your footwear. This isn’t just about shortening a pair of pants; it’s about taking control of your style, ensuring every garment you own fits you perfectly. By following this guide, you’ve not only hemmed a pair of jeans, but you’ve also mastered a practical skill that will serve you and your wardrobe for years to come.
