I became a big boy years ago...I was leaving for college and mom made sure I knew had to wash the range of clothing.
There are two refs in this house. But I would not entrust the intregrity of my uniform to that of the other sports ref. Besides, he has a tendency of losing (dont know how in this small house)/misplacing clothes that aren't his. Seeing that pants and the shirt are a bit vital, I'll do it myself.
But I have no tips, my shirt is a year old and not being worn this season, so it looks brand spankin new.
