Hi there! I made a scalloped template about and inch bigger than the cake and used it to cut out a circle of pink scalloped fondand and then placed it onto the white fondant with a little water. It was a bit fiddly and probably would have looked better if it had of been rolled a bit thinner though! Yes I used royal icing for the outline, but I did this after it was alraedy attached to the cake! Hope this helps x
