I covered the cakes in fondant then placed a piece of lace material on the cake (once the fondant set a bit). Then I "iced" the lace in royal icing using my icing spatula; then I gently peeled off the lace to reveal the pattern on the fondant. I piped the outlines of the flowers, etc. to give it depth. Note: I iced the tops of the cakes first then I took a separate piece of lace and wrapped it around the sides to ice, otherwise you'd end up with folds on the sides.
