3 wks to go, what have I forgotten?

I've got 23days to go. There are something clearly on the to do list. Confirm numbers and food, have hair and make up practice. But what are the rest of you up to? I've suddenly remembered I haven't tried the chair covers on the venue chairs to check they fit. Its ok I can do it on Sunday when we do final numbers but its got me worried what else I may have forgotten? So please ladies tell me Whats still on your to do lists?
