Taping up weight end of flag

[stegenref]

I've heard you're supposed to tape up the weighted end of your flag with white athletic tape, so the crowd doesn't see the yellow part sticking out of your pants. What's the best way to do that? And why don't the manufacturers just make that ball part white?

I tried taping up the weight on my flag last week right before a game and I thought it looked really sloppy.
