Is this enough change to take to festival?

It will be a small-ish festival in my hometown - a fall fesival. 11am-4pm on Sunday (but have to get to the bank in the next 2 hours!!!). They will have "free" face painting, so I expect my booth traffic to be a little quiet.

I will be charging $5 and $7 (mostly $5 faces)... this is a depressed area, with low disposable income.

I am thinking of taking $120 in one dollar bills and $50 in five dollar bills. I will make sure to put out a tip jar and give change back with some ones in, to encourage tipping. Does this change sound right? Should I take more, or different?

Thanks!

I usually take about $100 in $1s, so you should be fine.
Make sure to put a $5 & a $10 in your tip bucket. If you put only $1's in then you'll only get $1's.
