Many thanks for this, I've already had a read of that thread and yes it does have some useful tips. I was just really wondering if the zig zag was cut from sugarpaste or airbrushed? It's quite hard to tell from the picture
I don't think it airbrushed. The cake in my avatar is a big chevron pattern that I did from really thinly rolled fondant so you don't see the edges of the pattern that much. Check out Jessicakes blog about transferring chevron onto a cake using waxed paper. It really helps keep everything straight without stretching the pattern when applying it to the cake.
That's AMAZING! Thanks so much, this is definitely the route i'll go down.
