Tips

  • Minimize bulk around side seams by cutting interfacing slightly smaller.
  • Use a hair marker, finger pressing, or low-heat iron to press seams neatly.
  • Use a walking foot attachment for even fabric distribution when sewing zipper panels.
  • Leave a gap between zipper panel and zipper teeth (1/8 inch) to prevent fabric from getting caught.
  • Open zipper completely when assembling the bag to avoid bulkiness.

Common Mistakes to Avoid

1. Uneven Seam Allowance

Reason: Inconsistent seam allowance can lead to a bag that is lopsided or doesn't close properly.
Solution: Use a seam guide on your sewing machine or pre-press your seam allowance to ensure consistency.

2. Skipping Interfacing

Reason: Omitting interfacing results in a flimsy bag that loses its shape and structure.
Solution: Always fuse interfacing to the bag's exterior and strap pieces for stability and a professional finish.

FAQs
