If your phone case doesn’t have a mute button hole, no worries! See if there are any other holes in the case you’d be able to attach a charm to, such as the audio jack or charging port.

The beads or charm should not go through the hole.

The process of heating and pushing the needle through may take a few times, depending on the thickness of your case. Place the two holes about a centimeter apart. They’ll be close but not touching.

This method is riskier as the drill could scratch the case if you don’t have a steady hand, but is known to work on sturdier cases like those from OtterBox.

If you made two holes, slide the charm’s loop through both holes. [8] X Research source

Newer phones don’t have audio jacks, so this method works best on older models or Android devices.

Go for a charm that’s your favorite color, animal, or sport.

If you’re making a phone charm strap, use a cloth measuring tape to measure around your wrist. Think of this like starting a charm bracelet.

For example, if you want your charm to be 5 inches (13 cm) long, layout a row of beads that’s 5 inches (13 cm). Try using all different types of beads for a funky, colorful look everyone will be dazzled by. Consider a simple color pattern that matches your phone case for a more sophisticated look.

Use a transparent string to emphasize the color of your beads or go for a colored cord for even more fun. Keep the string on the roll while you thread the beads. This way, you’re sure to have plenty of string to finish your design. [13] X Research source

The first double knot creates the bracelet-like portion of the phone charm. The second double knot forms the loop to connect the phone charm to the phone. If making two double knots is tricky, use a keychain lariat by attaching the lobster claw end to the first double knot. [15] X Research source

Leave roughly 2 inches (5. 1 cm) of excess string. [17] X Research source

To make a surgeon’s knot, make an overhand knot, passing the right cord over the left and under. Then, pass the left cord over the right and wrap it under twice. [19] X Research source
