In this guide on How to Sew the Cutest Half-Moon Bag from Old Jeans, you’ll learn step-by-step how to cut, shape, and sew your bag using basic materials and tools. You don’t need a fancy sewing machine or advanced skills—just a love for DIY projects and the willingness to try something new. Let’s get started!
Before you begin, gather your materials. You’ll need:
Start by cutting your jeans along the seams to flatten out the fabric. This gives you large panels to work with.
Wash and iron the denim to remove any creases and to help it sew more easily.
Select parts of the jeans with fewer seams or details for the main body of the bag.
Use a round plate or draw a half-moon shape on cardboard to create a template.
Trace and cut two half-moon shapes from the denim and two from the lining fabric.
Take the two denim half-moon pieces and pin them with the right sides facing each other.
Sew around the curved edge, leaving the straight edge open. Use a ½-inch seam allowance.
Trim the curve with small snips to reduce bulk and help the fabric lie flat when turned.
Turn the piece right side out and press with an iron to smooth the seam.
If desired, topstitch around the curve for a more professional finish and added strength.
Repeat the same process for the lining fabric but leave a small gap in the straight edge for turning later.
Place the zipper along the straight edge of the denim piece, facing down toward the fabric.
Pin and sew one side of the zipper to the denim. Repeat with the second side.
Open the zipper halfway before attaching the lining to allow turning the bag later.
Pin the lining piece to the denim piece, right sides together, aligning the curved edges and the zipper.
Sew around the top edge, enclosing the zipper between the layers.
Turn the bag right side out through the gap in the lining. Stitch the gap closed by hand or machine.
Push the lining into the bag and press the edges flat for a neat finish.
Topstitch along the zipper edge for a crisp, polished look and better zipper function.
Add a strap using leftover denim or a ready-made strap. Attach with D-rings or sew directly to the bag sides.
Customize your bag with patches, embroidery, or fabric paint for added personality.
If your denim is soft, consider adding interfacing between the layers for more structure.
Enjoy your new bag and show it off! It’s a unique piece you made yourself—functional and fashionable.
Is this project beginner-friendly?

Do I need a sewing machine to make this bag?
While a sewing machine makes the process faster, you can sew this bag by hand using a strong backstitch and patience.
What kind of jeans work best for this project?
Midweight denim jeans with minimal stretch are ideal. Avoid overly worn-out fabric that may tear easily.
Can I make this bag in different sizes?
Absolutely. Use different templates to create small pouches or larger shoulder bags. Adjust the strap length and zipper accordingly.
What can I use the half-moon bag for?
It’s perfect for carrying essentials like your phone, wallet, and keys. Use it as a crossbody bag, makeup pouch, or gift bag.
Can I wash the finished bag?
Yes, but it’s best to wash it by hand to maintain the shape and avoid zipper damage. Air dry it flat.
