Thank you. Hi, after covering the cake with white sugarpaste I used a set square to lightly mark the lines - Measure and mark the lines at equal intervals depending on the size you want. Flip the set square over and mark the other way to form the criss cross pattern. Simply lightly press the edge of the set square into the sugarpaste. Then I used a stitch wheel tool to go over the light marks from the set square and finally ball tool to create the puffed out bit in the middle. It was pretty easy, not as complicated as it may seem.. Just took a little while. Afterwards I used my airbrush to colour the cake. If not using an airbrush you should colour the fondant first. Hope this helps. Feel free to ask me to explain more if you need me to.
