Preparing Your Denim

Preparing Your Denim
When sewing jeans, preparing the denim is an important first step. You’ll want to pre-treat, cut, mark, and interface the fabric properly before beginning construction. Preparing the denim ensures your jeans will have a professional finish. Carefully cut out the pattern pieces, transferring any markings to the wrong side of the fabric.

Use interfacing on key areas, like pocket fronts, to add body and structure. Mark buttonholes and other details clearly. Take time to prep the denim and your jeans will have a clean, crisp look. With the right preparations, you’ll achieve durable seams and smooth stitching.


Pretreat your denim by washing it separately in warm water without detergent or bleach first, so the fabric doesn’t bleed or shrink when you start cutting and sewing. This prewash helps stabilize the fabric and prevents indigo dye transfer and unexpected shrinkage later.

Once it’s pretreated, you’re ready to start cutting out your pieces. With pretreated denim and your pattern picked out, you’ll avoid headaches when constructing your jeans or denim jacket. Now you can start sewing your denim project with confidence, knowing your fabric’s prepped and ready to go.


Lay it flat and slice ’em on the grain. Lightweight denim can be cut on the fold. For heavyweights, slice layers flat – avoids sneaky stretching. Mark with chalk, match notches, mind the nap. Compare pattern pieces to your measurements – know your ease. Let those sharp shears glide – one clean slice.

Moving quickly keeps edges from fraying. Mark darts and pleats lightly – those get stitched away.


Soak your fabric in salt water to bring out the vivid blues and grays before carefully marking with tailor’s chalk.

  • Use water-soluble fabric chalk for precise lines.
  • First, test markings on fabric scraps.
  • Mark before washing to avoid fading.
  • Use tailor’s chalk for dark denim; use soap for light denim.

Follow the marked guidelines precisely. Strive for perfectly straight topstitching and creatively stitched pockets. Make small muslin tweaks to adjust the fit. Seek out quality rivets and hardware for an authentic look.


Next, be sure to cut the fusible tricot interfacing along the grainline, since denim needs stretch and flexibility. Pick the right interfacing to keep denim’s durability while allowing flexibility. Cut tricot on grain so it’ll stretch. Fuse gently to the wrong side per the instructions.

Your skills grow as you handle denim with finesse and purpose. With patience, the perfect pair awaits your practiced hands.

Interfacing Type Weight Uses
Fusible tricot Lightweight Shirts, blouses, lightweight jackets
Fusible weft Medium weight Casual jackets, pants
Fusible hair canvas Heavy weight Tailored blazers, suits

Sewing Techniques

Sewing Techniques
For sewing jeans, begin with the proper thread, needle, and pressing tools. Carefully finish the seams and hem using techniques friendly to denim for a sturdy, professional result.


You’ll want to stock up on this Coats and Clark extra strong thread for jeans to tackle your denim seams and hems. The early bird gets the worm! Opt for a poly-cotton thread in tan or golden hues to blend with decorative topstitching.

Match thread weight to needle size, such as a Jeans needle 80/12 works with Tex 30-40 thread. Increase tension slightly for balanced stitching. Poly threads withstand friction, but cotton gives a vintage look.


Use Schmetz’s specialty denim needles for sewing denim projects with ease. Selecting the right needle is essential for sewing denim. Schmetz Denim needles are optimized for piercing tough fabrics without bending or breaking.

Their larger eyes and scarves accommodate thicker threads. Pair these needles with durable threads to construct seams and hems that withstand wear without failing.


Properly pressing your seams keeps denim flat and prevents bulk.

  1. With the iron on the cotton setting, apply steam generously as you press seams open.
  2. Let sections cool between presses and use a clapper to set the seam.
  3. Give hems and waistbands an extra boost of steam before topstitching.

Seam Finish

Wowza! The faux flat-felled seams you finesse for your denim will be slick as a whistle and tougher than a two-dollar steak. After stitching the inseam, trim and grade the seam allowances. Fold one edge under and topstitch along the fold for a faux flat-felled seam.

Try mixing and matching techniques on each leg seam for interest. Add interest by stitching shapes or random lines on the legs before washing.


Once hemmed, your fashionable clothes will feel more finished and professional. When hemming jeans, finish raw edges with pinking shears or serging before folding up. Use clips, pins, or basting stitches to hold the hem in place. Consider a wider hem allowance, like 3/4 inch, to accommodate shrinkage.

For heavy denim, hammer the hem before sewing to flatten thick layers. Take care not to stretch the denim when stitching. Pressing the hem helps keep things tidy. Experiment with different hemming techniques and tools when making jeans at home.

Choosing a Jeans Pattern

Choosing a Jeans Pattern
When sewing jeans, choosing the right pattern is crucial for a great fit. Consider options like Leonora for a denim skirt or Weston for high-waisted shorts that suit your style and current wardrobe needs.

Mixing up the length and structure of sentences can help the writing sound more natural. Varying vocabulary by using words like ‘suit’ rather than repeating ‘fit’ makes the language more engaging.


You’ll find the Leonora skirt pattern works great for lightweight stretch denim. The loose gathering and exposed back zipper promote a sense of liberty in the design. The silhouette has a feminine fit-and-flare A-line shape that flatters most figures.

Play up the denim style with bold contrast topstitching on the waistband, hem, and side seams.

Pretty panel shaping provides visual interest. Optional pockets keep hands cozy. Hem seams showcase visible topstitching.

With some creative topstitching, the Leonora makes a chic denim skirt perfect for weekends and layering. Try adding funky pockets or exposed bias binding along the hem for extra flair. The pattern’s loose ease offers comfort while the stretch denim moves with you.

Sew it up in multiple washes of blue denim or branch out with black, white, or patterned lightweight denims too.


You can sew high-waisted denim shorts with the Weston pattern. Embrace the retro styling with a high waist, front pockets, and yoke detail. This unisex design allows you to play with denim shades, pops of color, and personalization touches like embroidered pocket flaps or shaped belt loops.

Practice professional techniques like flat-felled side seams, proper topstitching, and adding rivets or snaps.


Consider the lightweight denim dress of Adelaide as your next jeans project, bringing a breezy femininity through its flattering cut and carefree spirit. The Adelaide dress pattern offers adjustable straps and a full skirt with pockets for a fun denim dress.

Pair it with retro-inspired denim hardware and visible topstitching in a contrasting thread. Make fitting adjustments to the muslin before cutting into your lightweight denim fabric for the perfect breezy denim dress.
