Ori-Denim Obi Tote Bag

 

Ori-Denim Obi Tote Bag

The Ori-Denim Obi Tote effortlessly marries eco-conscious sustainability with high-fashion structural design. By repurposing post-consumer denim, this bag diverts textile waste from landfills while capitalising on the fabric’s inherent, hard-wearing durability. Denim's unique fading patterns ensure that every single bag possesses a one-of-a-kind, artisanal character. The brilliant geometry of the obi-fold construction distributes weight evenly across the shoulder, making it incredibly comfortable for daily use. Furthermore, the thick, folded layers create natural internal structural support without requiring heavy, synthetic stabilisers. It is a stylish, resilient, and conversation-starting accessory that proves circular fashion can be both deeply practical and exquisitely beautiful.

Fabrics & Required Materials

To achieve the perfect balance of structure and pliability, select your materials carefully:

• Outer Fabric: 2 to 3 pairs of old jeans (medium to heavy-weight, 10–14 oz). Avoid stretch denim; 100% cotton denim yields the best structural folds.
• Lining Fabric: 1 yard of mid-weight cotton canvas, sashiko fabric, or structured linen to contrast beautifully with the denim.
• Interfacing: 1 yard of medium-weight fusible woven interfacing (only needed if your recycled denim is on the thinner side).
• Thread: Heavy-duty jeans thread (topstitching thread) in gold, copper, or contrast cream, plus standard polyester thread matching the denim for structural seams.
• Tools: Denim sewing machine needles (Size 90/14 or 100/16), fabric chalk, rotary cutter and mat, quilting ruler, heavy iron, and strong sewing clips (wonder clips are highly recommended over pins).

Medium-Size Bag Measurements & Pattern Drafting

This pattern relies on a modular, geometric strip method inspired by azuma bukuro and origami folding techniques.

Seam Allowances

• Standard Seam Allowance: Included in the measurements below is a 1/2 inch (1.3 cm) seam allowance for all structural seams.
• Top Hem Allowance: 1 inch (2.5 cm) for the opening edges.

The Pattern Pieces

Cut the following rectangular panels from your salvaged denim and lining fabric.

Piece Name	Fabric Type	Dimensions (Width x Length)	Quantity
Main Obi Body Panel	Denim (Outer)	14 inches times 40 inches (35.5 cm} times 101.5 cm)	1
Main Obi Body Panel	Lining	14 inches times 40 inches (35.5cm times 101.5 cm)	1
Knotting Straps	Denim (Outer)	6 inches times 24 inches (15.2 cm times 61 cm)	2

Note on Drafting: If your recycled denim pieces aren't long enough to get a continuous 40-inch strip, colour-block your panel by piecing together smaller denim rectangles using a flat-felled seam until you achieve the total length. This actually enhances the reclaimed aesthetic!

Step-by-Step Construction Method

Step 1: Preparing the Denim & Lining

1. Deconstruct your jeans, cutting away bulky original seams, waistbands, and pockets.
2. Press the salvaged denim flat using high steam.
3. Cut out your Outer and Lining panels according to the dimensions above.
4. If your denim feels soft, fuse the interfacing to the wrong side of the denim outer panel.

Step 2: Creating the Obi Fold (Outer Shell)

1. Lay your denim main panel right side up horizontally.
2. Mark the panel into thirds along the length (roughly at the 13.3 -inch marks).
3. The Origami Fold: Take the bottom-left corner and fold it up diagonally to meet the top edge at the first-third mark. Pin along the top edge.
4. Take the top-right corner and fold it down diagonally to meet the bottom edge at the second-third mark. Pin along the bottom edge.
5. Fold the remaining outer segments inward, matching the raw edges. You will see a structural, slouchy envelope shape form with two pointed peaks at the top.
6. Clip the overlapping base and side seams together. Sew the raw bottom and side edges using a 1/2 inch seam allowance. Turn right side out and press the corners sharply.

Step 3: Constructing the Lining

1. Repeat the exact same folding and sewing process with the Lining fabric panel.
2. Crucial: Leave a 5 -inch (12.7 cm) opening unstitched at the very bottom centre of the lining fold to allow for turning the bag later. Keep the lining wrong side out.

Step 4: Assembling the Straps

1. Take the two strap pieces. Fold each in half lengthwise, right sides together.
2. Sew down the long raw edge and angle sharply across one short end (creating a pointed tie look). Leave the other short end open.
3. Trim the seam allowances, turn the straps right side out, and press flat. Topstitch along the edges for strength.

Step 5: Joining Everything Together

1. Baste the open, raw ends of your straps to the two pointed peaks of the outer denim bag shell, right sides facing.
2. Insert the right-side-out denim shell into the wrong-side-out lining shell (the bags should be right sides together, trapping the straps between the layers).
3. Align the top V-shaped opening edges and side peaks. Clip securely.
4. Sew entirely around the top perimeter of the bag opening using a 1/2 inch seam allowance.

Step 6: Finishing Touches

1. Pull the entire denim bag through the 5 -inch gap left in the lining.
2. Tuck the raw edges of the lining gap inside and edge-stitch it closed cleanly.
3. Push the lining down inside the denim shell. Iron the top edges of the bag carefully so the lining doesn't peek out.

Pro-Tips for a Beautiful, Professional Finish

• Pound Your Seams: Where multiple layers of denim meet, the fabric can become incredibly thick. Use a rubber mallet or a heavy wooden tailor's clapper to physically smash the thick denim seams flat before running them under your sewing machine foot. It prevents skipped stitches and broken needles.

• Embrace Sashiko Accents: Before folding the bag, use thick cream embroidery floss to hand-stitch geometric grids or traditional Japanese Sashiko ripples onto a section of the denim. It honours the heritage of the bag shape and creates gorgeous texture.

• The "Hump Jumper" Trick: When moving from a thin layer of denim to a thick, folded intersection, your presser foot will tilt backward and stall. Place a folded piece of cardboard or a scrap piece of denim under the back of the presser foot to level it out. Your machine will glide right over the hump.

• Lengthen Your Stitches: Use a standard stitch length (2.5 mm) for the internal structural seams, but dial it up to 3.5 mm or 4.0 mm when doing the decorative topstitching around the opening rim. Longer stitches look clean, intentional, and high-end on heavy denim.
