For starters, wrinkle your race number up a bit to help the number form to your body easier. Then, to properly pin the race number, push the pin through the number, then through the jersey, back through the jersey, and finally back through the number.

To pin on numbers, you should not use the provided holes. Instead, we want to “flat-pin” the number. Pull the jersey away from the rider’s body. Push the safety pin into the number and jersey. Once through the jersey, insert the pin about another 3⁄4 of an inch, then push the point out through the jersey and number.

You can pin your number on a flat surface as shown in the video, or while sitting in a chair, zip your jersey around your legs to mimic the stretch it gets when you wear it. It's personal preference whether you want to place the number above the pockets or over them.

The most secure method of pinning is to push the pin through both number and jersey layers twice. Do not pin with only one end of the pin through the number and out through the jersey. If there are pre-punched holes in the race number, ignore those: do not pin through the race number holes. 3. Use at least 6 pins PER NUMBER.
