the blue parts look like fondant and everything else looks like it's painted. you could probably free hand this design
very nice cake, very elegant... i love it... and great technique... i'm guessing here... the blue fondant are cut outs... then the lines are just lines... like embossing it... just like making the diamond patterns on princess cakes, not sure how you call them... if i'm going to make this cake, i'll print some stencils the size i like them to be. then cut the fondant and circles of course using circle cutters with little size difference. 'glue' the fondant cut-outs. and lastly, embossing or making lines the way just like the ones in this cake... then apply some luster dust or silver dusts to highlight the patterns... actually some parts of the 'blue' fondant cutouts i think are painted w/ silver dusts. well, it is just me... thats how i can do that cake. hope it make sense.... good luck on that one... hope you could post your finished cake =)
Thanks so much for your help!!! wish me luck, on this one !!!!
