How do SASE's work with baseballs?

I'm trying to send a baseball ttm to get signed and was wondering how the sase worked and the best way to send it.

a bubble mailer. put the baseball in the bubblemailer and put that one in a larger bubble mailer or manila envelope. I've only mailed a baseball once and that worked fine for me.
