My spill trick is the best!!!! (maybe/maybe not)
I save the cedar sheets from my boxes & get them from the local shops when I go. I cut them about 1/2" wide going with the grain. I have them in a neat little shot glass next to the humi so the stay dry as possible. When it's time to light up I grab 2 or 3 and fan them out. I then run a lighter over them being careful not to light them on fire just yet. Running fire over each side dries them out further prepairing them for the best possible burn. Anyone who has done this knows they go out too quick sometimes.
From here you can go one of two ways...
Either cut the cigar, toast and puff, or fully ignite the cigar's foot and then make your cut.
When I'm firing up with a torch I always fully ignite the foot then make my cut. This keeps nasty gasses from entering the cigar.
Hope this helps. It's a method I assembled from what I consider to be best practices from various videos and other smokers.
