Learn how to attach magnetic snap closures to bags with clear steps, common mistakes, and tips for choosing the right size for your project.
Quick Answer
To attach a magnetic snap closure, mark the placement, create small openings, insert the prongs, and secure them with the washers. Choose a size that matches your bag's fabric and intended use.
Choosing the Right Size and Placement
The size of the magnetic snap affects both the look and function. A smaller 14mm snap works well for wallets, small pouches, and inside pockets, while a larger 18mm snap provides a stronger hold for medium bags and tote openings. Think about the weight of the contents and the fabric thickness when selecting.
Placement matters: the snap should sit on the center flap or closure area, aligned so the two halves meet easily. For a flap bag, position the top half on the flap and the bottom half on the bag body, ensuring they align when closed.
Step-by-Step Attachment Guide
- Mark the Placement: On the wrong side of the fabric, mark the center point for each half of the snap. Use a fabric marker or chalk. Ensure the marks align when the bag is closed. Double-check alignment before cutting any holes.
- Create Small Openings: Use a sharp awl or small scissors to make a tiny slit or hole at each mark. The hole should be just large enough for the prongs to pass through, not bigger. If the hole is too large, the snap may shift or tear the fabric.
- Insert the Prongs: Push the prongs of the snap through the fabric from the right side to the wrong side. Make sure the snap is oriented correctly. Check that the snap faces the right direction before securing.
- Secure with the Washer: Place the washer over the prongs on the wrong side of the fabric. Press down firmly until the prongs fold flat against the washer. Use a hammer or pliers if needed. Ensure the prongs are fully flat to avoid scratching or snagging.
- Repeat for the Other Half: Attach the second half of the snap to the corresponding location on the bag body or flap, following the same steps. Test the closure to confirm the halves align and snap together smoothly.
