Step 1: Materials Needed:
You will need the following materials:
1. Safety Pins
2. Nail File
3. Nail Clipper
If you don't have any of these items lying around your house then any 99 cent store should carry them.
Step 2: What To Do:
Take your nail clipper and safety pin and clip off the very tip of the safety pin. Make sure that you leave enough for the safety pin to close back into place. If not, it will be useless.
Do the same for the other safety pin.
Then, lightly file the ends to make sure that there is nothing rough left. Make sure that it is smooth before you decide to try them out.
