I recently made my daughters cake, a double barrel which was at least 23 cm high (pisture in my cake portfolio), it wasnt easy but I covered it all in one go with one piece of fondant. Not the best job, next time will be better, I did watch the following video first which goes through covering a double barrel but also sharp edges, I have to say I wasnt game to follow her recommendation for the sharp edges for such a high cake but may try with a smaller one in future – good luck!
