3 Tips for Inserting a Magnetic Snap

Have you ever made a beautiful handbag only to have the magnetic snap rip out as you are using it? Well today I’m going to show you a few things you can do to make inserting a magnetic snap easier and ensure your snap is able to withstand the wear and tear of everyday use.

Tip #1 ALWAYS use an extra placement disc to protect your fabric.

Each magnetic snap comes with 4 parts: two sides with prongs and 2 metal discs. Did you know you’ll also need to cut an extra disc that is a little bigger than the metal disc? This extra disc prevents the sharp edges of the metal disc from cutting into the fabric as you open and close the snap during use.

I like to use a piece of a plastic folder because it's thin and flexible, but you can also use cereal cardboard, plastic shelf liner, or felt instead. Just draw lines and cut slits in your extra disc to match the placement disk. You may ask, “What if I already used interfacing on my fabric?” Add this extra disc anyway, it really helps! 

Tip #2 Use a Seam Ripper to cut the perfect sized slits.

To install your snap, you’ll need to cut a small slit in your fabric to slide the prongs through. It is really easy to cut these holes bigger than you want to, especially if the tips of your scissors aren’t too sharp. Instead of cutting the slits with scissors you can use a seam ripper to cut them to EXACTLY the right size. Just slide the point of the seam ripper in one end of the drawn slit line and out the other, just like a pin, and give it a push.

This should work even if you’ve fused interfacing to the lining. Try it on a scrap fabric to make sure your seam ripper is sharp enough but it should be. You can also use it to cut the slits in your extra placement disc!

Tip #3 - Use a tool to bend the prongs and save your fingers.

Once you have all the parts of the snap together the final step is to bend the prongs out so they lay flat. Sometimes it is really tricky and painful to get the prongs to bend using your fingers, especially if you are using a high quality snap.

Instead of using your fingers, save your hands and grab the handle of any tool (like a screwdriver) and press it down between the prongs and they will easily start to bend. You can use the handle to press them all the way flat or use your fingers to finish them off now that the hard work is done!

That’s it! I hope these tips will help you on your bag making journey.
