What did the two finishers think of it?

Coffee spills are the worst kind of helpful. Happened to me last year with a site plan. Let the paper dry completely before you try to erase the stain, or you'll tear it. A hairdryer on low works if you're in a rush. Maybe do a quick trace of the corrected area on a fresh sheet before the old one gets too brittle? What are you using to fix the line work, ink or pencil?

Paulm95, your point about chasing clippings reminds me of this time we tried a backyard movie night without checking the forecast. A huge gust came out of nowhere and sent the screen flying into the neighbor's pool. Everybody just laughed it off though, and we ended up having a better time because of the chaos. That's the thing with no-plan events, they either go perfectly smooth or totally off the rails, but both ways make for a good story. The lack of pressure lets people roll with the punches instead of getting upset. I'd take that messy memory over a stiff, booked-up party any day.

Maybe for some folks like leowest's grandpa, it's just coffee, but for others the whole ritual is the actual point.

How'd you figure out the wiring?
