DS1 is 3 soon and wants a double decker bus for a cake. I can't find anyone locally to order one from so I've read up tips on MN, and I'm ready to work out dimensions of bus, then bake a moist vanilla cake or a nigella buttermilk cake, freeze, cut, crumb icing (freeze again?), then roll out my icing and that's where I'm lost.
Most howto's I've seen involve draping the fondant over the cake and smoothing, but
- if you cut out those windows before you'd get it all distorted, - if you cut them out afterwards it would be too easy to cut into the black layer of icing below (unless maybe there's some paper lining that you pull out afterwards?) - if you make flat panels and cut the windows all nice and square then how do get rid of the seams where the panels are joined
