I've been asked to do something similar to the cake below. I'm not sure what to do about the middle tier - what kind of vines/branches do you think it is? It looks like real ones, but I'm not sure where to get something like that. Any suggestions would be appreciated!

I like this look. You might find something in the dried section in Michaels or acmoore?good luck. Also walmart flower section. It can be similiar, then as the recipient about it.
