If you have 5/7 charges to start the day, charge up with two quests, place the charged sticker, then do the last quest, which will leave you with 6/7 charges. The next day you can, if you do one quest, place charged sticker, and do the last 2 quests, and place another charged sticker, that is 2 charged stickers that day.

And that is how you place 3 charged stickers in 2 days.

If you wanted to just do an entire month of charged stickers to a creator, technically, next month, you should be able to get either 46 charged stickers for December, or any 31 day month.

Now you know, and have an amazing day, you wonderful people!
