I have to make a Michael Kors purse cake in two weeks, the only thing I'm not sure how to do is the MK logo thats all over the purse. Any advise on how would be the best way to do that?

Can you post a direct link to the bag you would like to replicate? There are many and to be able to give you pointers, we would need to know which one it is.
Offhand I's cut them out from gumpaste and paint silve when dry. I find if I paint them silver (lustre dust and vodka, let them dry until still slightly tacky, and them brush on dry lustre, it brings out the bling much more)

You mix the dust with vodka? Can you explain that process more. Thank you!
