I did this one for a customer last weekend. I had to change it up a little from how the actual bottle comes as usually it is standing up in the box but for this to work I had to lay it down. My customers husband is a huge Crown Royal XR fan so she just knew this had to be his cake. I tried to get all the details of the bottle and the box even down to the super fine texture on the sides of the box. I actually molded the real glass stopper then created it in isomalt to get everything as realistic as possible.
