Preparation and Safety Guidelines

Tools Needed
  • Fabric (0.8 meters of ripstop nylon or cotton)
  • PDF Pattern
  • Elastic (7 inches)
  • Scissors
  • Pins
  • Sewing Machine
  • Tape Measure
  • Iron
  • Serger (optional)
Safety Guidelines
  • Always thoroughly wash your reusable bags after each use, especially if you've carried raw meat or produce. Bacteria can easily breed in damp fabric.
  • Inspect your bags regularly for tears or holes. Damaged bags can easily rip, causing spills and potentially contaminating your groceries.
  • Avoid overloading your reusable bags. Overstuffed bags can tear or become difficult to carry, increasing the risk of dropping groceries and injuring yourself.

Step-by-Step Instructions

  1. Prepare Pattern and Fabric

    • Print and assemble the free PDF pattern, ensuring edges align perfectly.
    • Fold fabric in half lengthwise, matching selvage edges. Place pattern pieces with handles between each other to maximize fabric use.
    • Measure and pin grain lines to ensure pattern pieces are parallel to the selvage and not overlapping. Pin the rest of the pattern pieces and cut them out.

  2. Sew Bag Body

    • Mark the center point of the curve (notch) on both the front and back pattern pieces using a pin or tracing wheel.
    • Place front and back bag pieces together with right sides touching. Pin along the three long edges and sew with a 5/8 inch seam allowance, leaving corners unsewn.
    • Repeat step 5 for the facing piece. Finish seams with a serger or zigzag stitch to prevent fraying.
    • Pin the corners of the bag, matching seams. Sew across the short edge to give the bag dimension. Repeat for all four corners.

  3. Attach and Finish Straps

    • Turn the bag right side out. Attach the elastic to the center point of one side of the bag, sewing along the 1/10 inch line, reinforcing the stitch to create extra strength.
    • Attach the facing piece over the bag, aligning middles and seams. Sew along the 5/8 inch seam allowance, stopping at marked points three and a half inches down from the top. Repeat the sewing on other side seams, leaving the straps open at the top and making chalk marks 3.5 inches from the top of the straps.
    • Clip concave curves to allow the curve to sit smoothly. Flip the straps right side out and turn the facing to the inside.
    • Press edges and sew the straps together, leaving an opening at the top. Turn under the seam allowance and press it flat.

Tips

  • Use durable fabric like ripstop nylon or cotton, or upcycle an old sheet.
  • Use a matching thread for a seamless finish.
  • Don't clip your shears past the stitching line when clipping curves.

Common Mistakes to Avoid

1. Using unsuitable fabric

Reason: Choosing a fabric that's too thin, flimsy, or prone to tearing will result in a weak and unreliable bag.
Solution: Select durable, tightly woven fabrics like canvas, denim, or heavy-duty cotton.

2. Incorrect seam allowance or poor stitching

Reason: Insufficient seam allowance or loose stitching will lead to the bag ripping easily under stress.
Solution: Use a generous seam allowance (at least ½ inch) and reinforce seams with double stitching or a zigzag stitch.

3. Forgetting to reinforce stress points

Reason: Areas like handles and bottom corners experience the most wear and tear; neglecting to reinforce them weakens the bag.
Solution: Add extra layers of fabric or use interfacing to strengthen the handles and bottom corners.

FAQs

What type of fabric is best for making a reusable grocery bag?
Durable, washable fabrics like canvas, cotton duck, or even sturdy quilting cotton work well. Avoid lightweight fabrics that might tear easily under weight.
How do I ensure my homemade bag is strong enough to carry heavy groceries?
Use double or triple stitching, especially along the seams and stress points like the handles. Choose a strong, tightly woven fabric and consider reinforcing the bottom with an extra layer of fabric.
