Laundry Tip!

In order to keep your patches from running red dye on your white shirt...

Soak your MHSAA patch and your flag insignia (if you have one) in 1/2 cup of vinegar and 1 cup of cool water. Soak overnight in separate containers, rinse and air dry before attaching them to your white shirt.

HELP! I'M STUCK IN TRAFFIC! Remember the importance of carrying your schedule and the phone numbers of your fellow officials. Call or text ahead if you know you are going to be delayed. In addition, if you are the one that's already at a match, leave your phone out until your crew has arrived. They may be trying to call you! Once the whole crew has arrived, turn it off and put it away.
