How to Sew a Drawstring Bag with Flat Bottom

Sewing a drawstring bag with a flat bottom is a practical and rewarding project for both beginners and experienced sewers alike. This guide will walk you through every step of the process, from selecting the right materials to finishing your bag with professional touches. By the end, you'll have a stylish and functional bag that's perfect for everyday use.

Step 1: Gathering Materials

1. Fabric: Choose a sturdy fabric like canvas, denim, or cotton. For a more decorative touch, you might opt for patterned or textured fabric. 2. Lining Fabric: To add structure and a finished look to the inside of your bag, use a complementary or contrasting lining fabric. 3. Drawstring Cord: A strong cord or rope that matches your fabric is essential. Common choices include cotton cord, nylon rope, or even leather strips. 4. Thread: Use a heavy-duty thread that matches your fabric color for durability. 5. Tools: Scissors, pins, a ruler or measuring tape, a sewing machine, and an iron are necessary for this project.

Step 2: Cutting the Fabric

1. Bag Body: Cut two rectangular pieces from your main fabric for the bag's front and back. For a flat-bottomed bag, consider dimensions that suit your needs, such as 14” x 16” for a medium-sized bag. 2. Bottom Gusset: To give your bag a flat bottom, cut a separate piece that will form the base. For instance, a piece measuring 14” x 4” for the gusset will work well with the main fabric pieces. 3. Lining: Cut similar pieces from your lining fabric, ensuring you also cut a gusset for the lining.

Step 3: Assembling the Bag

1. Create the Gusset: Sew the bottom gusset to the main fabric pieces. Place the gusset piece between the front and back pieces, aligning the edges. Use a ¼” seam allowance and stitch along the edges. 2. Sew the Sides: With right sides together, stitch the sides of the bag, making sure to reinforce the seams. 3. Attach the Lining: Repeat the process for the lining, then turn the bag inside out, and place it into the lining. Align the top edges of the main fabric and lining, pin them together, and sew around the top edge, leaving a small opening for turning.

Step 4: Creating the Drawstring Casing

1. Prepare the Casing: Fold the top edge of the bag down about 1 ½” to create a casing for the drawstring. Press with an iron to create a crisp fold. 2. Sew the Casing: Stitch around the folded edge, leaving a small gap to insert the drawstring.

Step 5: Inserting the Drawstring

1. Thread the Cord: Use a safety pin or a drawstring tool to thread your cord through the casing. Make sure the cord is even on both sides. 2. Secure the Ends: Tie knots at the ends of the drawstring to prevent it from slipping out of the casing.

Step 6: Final Touches

1. Press the Bag: Use an iron to press all seams and the top edge of the bag to ensure a crisp, professional finish. 2. Inspect and Adjust: Check for any loose threads or uneven areas. Make adjustments as needed to ensure the bag looks polished.

Troubleshooting Tips

1. Uneven Gussets: If the gussets are not aligning correctly, trim any excess fabric or adjust the seam allowance. 2. Drawstring Issues: If the drawstring is too tight or loose, adjust the casing or re-thread the cord to ensure proper fit.
