During the height of my votive selling days I would put a typed instruction sheet in the box and the small sticker instruction on the bottom of each votive. The votives were put upside down in the box so they were visible. The instructions emphasized what Stella said, to baby sit it once it was 3/4 of the way burnt, to straighten and trim the wick after extinguishing. I also sold votive holders that fit the candles best and candle quenchers to extinguish it properly. The instructions are basically the same things I tell my container customers.
