Welcome to the Cake Decorators Q&A

does anyone have a list of ingredients for this cake?

Hi britishbird

The cakes are any of your choice, I think Paul says in the tutorial the sizes. The amounts for the roses is a guestimate which you can see here http://www.cakeflix.com/questions/quantities-for-rose-wedding-cake.
The information for the boards and ribbons is also in the tutorial. There are other answers on various queries for this cake which you can see by putting in the search box ‘Bride and Groom Rose wedding cake’. Hope this helps.
