Here's a link for a fondant pleat tutorial which looks really helpful for what it looks like you need
I would spray your finished cake with silver lustre dust to make it give that shiny effect and if you've got an airbrush kit then you can use the pearl effect for the same effect. I hope this helps
if you do it the other way and do it all the way around you'd get the same effect x
Thanks Jess for your link, I was over thinking the whole thing, anyway it went down a storm at the wedding yesterday so all good.
AAwww good I'm so glad and it's so easy to do so it's all good x
