🎒 DIY Mini Denim No-Zipper Phone Crossbody Bag from Old Jeans

🧵 What You’ll Need:

  • 1 pair of old jeans

  • Fabric scissors

  • Needle and thread or sewing machine

  • Measuring tape or ruler

  • Chalk or fabric marker

  • Iron (optional but helps)

  • Pins or clips

  • Snap button / magnetic clasp / velcro (for closure)

  • Strap options: Old bag strap, denim strip, ribbon, or braided cord


✂️ Step 1: Choose and Cut Your Denim

  1. Pick a Leg: Use the bottom part of one leg (thigh area works great for size).

  2. Measure Your Phone: Add about 1 inch (2.5 cm) extra on all sides for seam allowance.

    • Example size: If your phone is 6” x 3”, cut a piece 8” x 5”.

  3. Cut 2 Pieces: One for the front and one for the back.

  4. Cut a Flap (optional): Cut a small piece (about 3″ x 5″) that will be folded over to close the top.


🧵 Step 2: Sew the Body of the Bag

  1. Place Right Sides Together (the side you want showing).

  2. Sew 3 Sides:

    • Sew both sides and the bottom.

    • Leave the top open.

  3. Trim and Turn Inside Out:

    • Trim corners at a diagonal (don’t cut through seam).

    • Turn the bag right side out and press flat.


🔒 Step 3: Add the Flap Closure (Optional but Cute)

  1. Attach the Flap to the back top edge of the bag.

  2. Sew Across the Top Edge of the Flap.

  3. Fold flap over the front and mark the spot for your closure.


🔘 Step 4: Add a Closure

Choose what’s easiest for you:

  • Magnetic snap – Easy and sleek.

  • Snap button – Basic hand-sewing.

  • Velcro – Easiest to sew, ideal for beginners.

Sew each side onto the flap and the front of the bag.


🪢 Step 5: Make the Crossbody Strap

You’ve got options:

  1. Use old belt, purse strap, or cord.

  2. Make a denim strap:

    • Cut a long strip from the jeans (~1.5” wide, 40–50” long).

    • Fold edges inward, then in half, and sew the long edge shut.

Attach the strap securely to the sides (sew into seams or use loops and rings if available).


🎉 Step 6: Final Touches

  • Add any decorations: embroidery, patches, beads, or fabric paint.

  • Iron it for a crisp look (optional).


✅ Tips

  • Denim can fray—consider finishing raw edges with a zigzag stitch or binding.

  • Reinforce the strap area with extra stitching.

  • You can reuse back pockets of the jeans for extra outside storage.


👜 Finished Size Example:

  • Holds most standard phones, a card or two, and some cash.

  • Roughly 7″ tall x 4″ wide.
