trial tipping question (again sorry)

okay first off i'd like to say sorry for not being around as much as used to. i have been so bogged down with work from school i feel like i'm always behind and trying to catch up. this site is SUCH a distraction and i'm trying to be good but it's hard. okay. enough about that...

TIPPING!!!

i have a trial this weekend. both hair and makeup with dina and april. my mom is also going to have a trial with me (she's like never had anything done in her life like this so i figured she'd better have a trial!)

how much should i tip? thanks for your opinions ladies in advanced!!!

SMOOCHES!!
