Preparing Your Fabric & Cutting Pieces

Before you start sewing, accurate cutting is crucial. A typical finished bento bag measures around 12″ wide x 12″ high, but you can adjust these dimensions to suit your needs. Remember to add seam allowances!

  1. Wash and Iron: Pre-wash and iron your fabrics to prevent shrinkage after sewing.
  2. Cut Fabric Pieces: Cut the following pieces:
    • Outer Fabric: Two squares, 13” x 13” (includes 1″ seam allowance on all sides)
    • Lining Fabric: Two squares, 13” x 13”
    • Interfacing: Two squares, 13” x 13”
    • Handles: Two strips, 2” x 24” (adjust length for desired strap length)
  3. Apply Interfacing: Fuse the interfacing to the wrong side of the outer fabric pieces. This adds structure and stability.

Constructing the Bag Body

Phase 1: Preparing the Outer Bag

  1. Hem the Top Edge: Fold the top edge of each outer fabric piece down 1/2″ twice, pressing each fold. Then, stitch along the folded edge to create a clean hem. This will be the top opening of the bag.
  2. Attach Magnetic Snap/Button: Follow the manufacturer’s instructions to attach the magnetic snap or button to the hemmed edge of one outer fabric piece. Position it centrally.

Phase 2: Assembling the Bag

  1. Place Right Sides Together: Place the two outer fabric pieces right sides together, aligning all edges.
  2. Sew the Sides and Bottom: Sew around the sides and bottom with a 1/2″ seam allowance, leaving the top edge open. Backstitch at the beginning and end of each seam for reinforcement.
  3. Clip Corners: Clip the corners diagonally to reduce bulk when turned right side out.

Phase 3: Lining the Bag

  1. Repeat Steps 1-3 with Lining Fabric: Repeat the hemming, attaching the closure, and sewing process with the lining fabric pieces, but leave a 4-6 inch opening in the bottom seam of the lining. This opening is essential for turning the bag right side out.

Creating and Attaching the Handles

Phase 1: Preparing the Handles

  1. Fold and Press: Fold each handle strip in half lengthwise, wrong sides together, and press.
  2. Fold Again: Fold each long edge towards the center crease and press again.
  3. Fold One Last Time: Fold the handle in half again, enclosing the raw edges, and press.
  4. Topstitch: Topstitch along both long edges of each handle to secure the folds.

Phase 2: Attaching to the Bag

  1. Position Handles: Pin or clip the handles to the outer fabric, evenly spaced on either side of the bag. The handles should be positioned approximately 3-4 inches from the side seams.
  2. Secure Handles: Stitch the handles securely to the bag, reinforcing the stitching at the attachment points.

Finishing the Bag

  1. Turn Right Side Out: Carefully turn the bag right side out through the opening in the lining.
  2. Close the Lining Opening: Hand-stitch the opening in the lining closed using a slip stitch.
  3. Insert Lining: Push the lining inside the outer bag, ensuring the corners are neatly aligned.
  4. Press: Press the bag to give it a crisp, finished look.

Pro Tips

  • Fabric Choice: Consider using waxed canvas for added water resistance.
  • Handle Variations: Experiment with different handle materials like leather, webbing, or even rope.
  • Pocket Addition: Add an internal pocket for small items like keys or phones.
  • Quilting: Quilt the outer fabric for a more textured and decorative look.
  • Reinforced Seams: Use a narrower seam allowance (1/4″) and reinforce seams with a zig-zag stitch for extra durability.
  • Pattern Placement: Pay attention to pattern placement when cutting your fabric for a visually appealing result.
  • Interfacing Weight: Use a heavier weight interfacing for more structure, and a lighter weight for a softer feel.

FAQ

Q: Can I use any type of fabric?

Q: How do I adjust the size of the bag?

A: Simply adjust the dimensions of the fabric pieces accordingly. Remember to add seam allowances.

Q: My magnetic snap isn’t holding. What should I do?
