How to Sew a Denim Tote Bag from Old Jeans | Full Sewing Tutorial with Pattern

Upcycle your old denim jeans into a stylish, sturdy, and environmentally friendly tote bag! This DIY denim tote project is perfect for beginners and intermediate sewists who want to repurpose worn-out or no-longer-worn jeans into something practical and fashionable.

In this tutorial, we’ll walk you through every step — from selecting the right pair of jeans to creating a functional pattern, cutting your fabric, and sewing your tote bag. You don’t need a commercial pattern; you’ll draft your own using the jeans themselves.

✂️ Materials & Tools Needed

Materials:

1–2 pairs of old jeans (adult size works best)
Matching or contrasting thread
Optional: cotton lining fabric (fat quarter or scrap cotton)
Interfacing (optional for added structure)
Webbing or additional denim for handles

Tools:

Sewing machine
Fabric scissors or rotary cutter
Seam ripper
Pins or sewing clips
Measuring tape or ruler
Chalk or fabric marker
Iron & ironing board

🧵 Step-by-Step Instructions

✅ Step 1: Choose and Prepare Your Jeans

Pick an old pair (or two) of jeans that are no longer wearable — holes in the knees or worn cuffs are okay since you won’t be using those parts.

🧼 Wash & Iron

Wash your jeans thoroughly to remove dirt and soften the fabric.
Iron the denim flat to remove creases and make cutting easier.

✂️ Deconstruct the Jeans

Use your scissors or seam ripper to:

Cut along the inner leg seams and crotch seam to open up the legs.
Remove waistbands, pockets, belt loops if you want to reuse them later.
Cut off frayed edges or worn-out patches.

You should now have large, flat panels of denim to work with.

📝 Step 2: Create a Simple Tote Bag Pattern

You don’t need a printed pattern — here's how to draft your own.

Bag Body:

Decide on your tote size. A standard tote size is:
- Width: 15 inches (38 cm)
- Height: 14 inches (35.5 cm)
- Depth (Gusset): 4 inches (10 cm)
Cut two rectangles of denim: 16" x 15" each (add ½" seam allowance on all sides).

Handles:

Cut two strips of denim or webbing: 22" x 2.5"
If using denim, fold and press the strip in half lengthwise, then fold raw edges inward and topstitch both edges to make sturdy straps.

Optional Lining:

Cut two rectangles of lining fabric using the same dimensions as the bag body.

Optional Pocket:

Use a back pocket from the jeans as an interior or exterior pocket.
Or cut a 6" x 6" square and hem the edges to create a patch pocket.

✂️ Step 3: Cut Out the Fabric

Lay your pattern pieces on the denim and trace with chalk or a fabric marker.
Cut out all components — 2 outer panels, 2 handles, 1–2 pockets (optional), and 2 lining pieces (if using).

Tip: Place thicker seams at the bottom or top of the bag for visual interest and added structure.

🧵 Step 4: Assemble the Outer Bag

1. Attach Pocket (Optional):

Pin your pocket onto one of the outer panels.
Stitch along the sides and bottom, reinforcing the top corners with a backstitch or bar tack.

2. Sew the Outer Bag:

Place right sides together of the two outer panels.
Sew down both sides and the bottom with a ½" seam allowance.
Press the seams open.

3. Box the Corners (Gusset):

Pinch each bottom corner to form a triangle, matching side and bottom seams.
Measure 2" from the point and draw a straight line.
Sew along the line and trim excess fabric.
This gives the bag its depth and boxy shape.

🧵 Step 5: Assemble the Lining (Optional)

If you’re lining your tote:

Repeat the same steps as the outer bag with your lining fabric.
Leave a 3" gap at the bottom seam for turning later.

🧵 Step 6: Prepare the Handles

If you’re using denim:

Fold each strap strip in half lengthwise.
Press, open, and fold both raw edges inward to the center.
Fold in half again, enclosing raw edges.
Topstitch both long edges for a clean, sturdy handle.

🧷 Step 7: Attach the Handles

Turn the outer denim bag right side out.
Measure and mark handle placements — 4" from each side edge.
Pin the ends of one strap 4" apart on the front panel, with raw ends aligned with the top of the bag.
Repeat for the back panel.
Make sure straps aren’t twisted.

🪡 Step 8: Assemble Bag & Lining Together

Place the outer bag inside the lining, right sides facing each other. The handles should be sandwiched in between.
Align top edges and side seams. Pin all around the top.
Sew all around the top edge using a ½" seam allowance.

🔁 Step 9: Turn the Bag Right Side Out

Pull the entire bag through the gap in the lining.
Push the lining into the bag and smooth it out.
Press the top edge neatly.

🧵 Step 10: Topstitch the Top Edge

Topstitch ⅛"–¼" from the top edge around the entire opening.
This adds a professional finish and secures the lining and straps in place.

🧵 Step 11: Close the Lining

Sew the gap in the lining closed with a small seam or hand-stitch with a ladder stitch.

✅ Finished!

You’ve just transformed your old jeans into a gorgeous, reusable denim tote bag! It’s washable, durable, and perfect for groceries, books, beach trips, or daily errands.

🧠 Bonus Ideas & Variations

Patchwork Style: Use different shades of denim for a boho or color-blocked look.
Decorative Details: Add embroidery, appliqué, or fabric paint.
Add a Zipper: Sew in a top zipper or interior zipper pocket for security.
Use the Waistband: Repurpose the waistband as a decorative detail or shoulder strap.
Add Button or Snap Closure: For a minimalist closure, use magnetic snaps or buttons.

🧼 Care Tips for Denim Tote

Machine wash cold with similar colors.
Hang to dry or tumble dry low.
Avoid bleach to maintain the denim’s original color.
