Step 2 : Ice your cake and set it aside in the freezer for 10 mins. The best part about this cake is that, your icing doesn't have to be perfect (not even close to how it looks in the picture above), as you would be doing a basket weave on top.
Step 3 : Spray a little water around the icing so that the icing for basket weave sticks to the cake. Decorate your cake with a colored or white icing to create a basket weave.(http://www.wilton.com/technique/Basketweave)
Step 4 : I used royal icing mixture (http://www.wilton.com/recipe/Royal-Icing) and colored it purple. To make the roses, I used the Wilton technique (http://www.wilton.com/technique/Roses) and set them aside to dry for a day. I also made a dozen rose buds using the same icing colo for the side decorations. The wilton technique that I used is provided here http://www.wilton.com/technique/Rosebud. Once the roses and the buds dry completely, it can be placed it on the cake. Draw the tendrils using tip #2 and leaves using tip #2 and green buttercream icing. And viola.. That's it !
