This is the easiest method, ideal for tote bags or adding basic organization.

Step 1: Measuring and Cutting the Fabric

  1. Measure the width and height of the inside of your bag where you want the divider to go.
  2. Add 1 inch to both dimensions for seam allowance.
  3. Cut a piece of fabric (and interfacing, if using) to the calculated size.

Step 2: Applying Interfacing (Optional)

  1. If using interfacing, iron it onto the wrong side of your fabric according to the manufacturer’s instructions. This will give the divider more structure.

Step 3: Finishing the Edges

  1. Fold over each edge of the fabric by 1/2 inch and press with an iron.
  2. Fold over again by another 1/2 inch and press.
  3. Pin the folded edges in place.
  4. Sew along the folded edges, close to the inner fold, to create a clean finish.

Step 4: Inserting the Divider

  1. Simply slide the finished divider into your bag. You may want to secure it with fabric glue dots or a few hand stitches at the bottom corners to prevent it from shifting.

Pro Tips for Sewing Bag Dividers

  • Use durable fabric: Choose a fabric that can withstand regular use and the weight of your belongings.
  • Reinforce stress points: Add extra stitching at corners and areas where the divider will experience more wear and tear.
  • Consider bag lining: Use a fabric that matches the bag’s lining for a seamless look.
  • Pre-wash fabric: This prevents shrinkage after sewing.
  • Test fit frequently: Check the fit of the divider throughout the process to ensure it fits properly.
  • Use contrasting thread: If you want the stitching to be visible, use a contrasting thread color for a decorative effect.

When to Seek Professional Help

  • Complex bag construction: If your bag has a complicated lining or structure, it’s best to consult a professional seamstress.
  • Expensive bag: If you’re working with a high-value bag, you don’t want to risk damaging it.
  • Lack of sewing experience: If you’re new to sewing, a professional can ensure a clean and durable result.
