When you diy how do you make sure it is cleaned up afterwards?

Hi ladies,
I have been at a loss for direction when going the DIY path. I have a florist and an event decorator but the small in between details I would love to do myself... because who wants to pay for these fun DIY projects?! My question is... for things like, decor on the chairs that line the ceremony walk way, maybe 8-10 chairs total, or the added center piece details, the seating charts using wine bottles. Just little details like this, who or how do you make sure it is cleaned up by the end of the night on your wedding night when you may or may not be consumed by having such a good time as a bride you may forget to grab something at the end of the night? Is there a mystical creature that can do this? Or do I have to make a reminder on my phone to STOP having fun and make my rounds to collect all my DIY pieces? Lol this is so weird to ask but something I have been worried about. I am having my wedding at a venue that requires everything to be cleaned up by the end of the night. No chance to visit the next day... thanks for anyone who can offer ideas or insight. It's such a simple weird questions but something I am so confused about how other brides do it?
