Maybe a variation of 16 #18 and #17 where you put nicol interiors on the same line, have that be a banner that extends out both sides of the circle, then have a styled N or NI where the current NICOL is so that the N or the NI could stand alone as a favicon or emblem stamped on a candle. Let me know if this needs further clarification.
For #16 can you have the outer beige stroke be small circles in the same color opposed to a solid line?
