   • Determine where you want the magnetic clasp—typically centered on the flap and corresponding body of the bag.
   • Use a ruler to measure and mark the exact center points on both the flap and the main panel.
   • Double-check alignment by gently folding the flap over to ensure the marks line up perfectly.
   • Mark both spots with fabric chalk or a washable marker for visibility.
3. Install The Snap Button On The Fabric

   Accurate installation ensures long-term durability and alignment:

   • Separate the magnetic snap components. Place the front half (usually the cap with prongs) on the outside of the bag flap at the marked spot.
   • Apply a small amount of adhesive to the back of the snap cap to prevent shifting during installation.
   • On the inside of the flap, align the magnet piece so it sits directly behind the front cap.
   • Repeat the process on the opposing side (main bag panel), ensuring the magnet and metal disc are positioned to attract when closed.
   • Allow adhesive to set for 5–10 minutes to secure initial placement.
4. Attach The Snap Button

   This step secures the snap mechanically for lasting performance:

   • If using pronged snaps, use a hole punch or awl to create small openings through the fabric where the prongs will pass through.
   • Push the prongs through the fabric from the front to the back.
   • On the back side, place the washer or backing plate over the prongs.
   • Use needle-nose pliers or a snap-setting tool to bend the prongs outward firmly against the washer, ensuring a tight hold without tearing the material.
   • For tool-free snaps (common in craft kits), simply press both halves together until they click securely into place.
   • Avoid excessive glue on moving parts—only use adhesive around the base, not on the magnet itself.
5. Final Adjustments And Testing

   Ensure your magnetic clasp functions smoothly and looks professional:

   • Allow adhesive to cure fully (typically 24 hours) before heavy use.
   • Test the closure by opening and closing the flap several times. The magnets should align naturally and snap together with a soft click.
   • If the snap feels weak, check alignment—misaligned magnets reduce holding strength.
   • For thin or delicate fabrics, reinforce the back with a small patch of interfacing or felt to prevent tearing over time.
   • Inspect for any excess glue residue and clean with a damp cloth if needed.
