possibly the pattern has been painted on?
Very striking cake. The 1st thing that comes to my mind is a chocolate transfer. The bottom of each tier deffinatly looks like ribbon. Some of it looks like random freehand scrollwork. i'm sure someone on here my have better answers. Looking forward to seeing your finished pics.
The stripes look like ribbon with a small bow in the front. The designs look hand painted to me. Loks like it was done freehand with gel colors.
I agree.. Looks painted.. Very nice.
