That is going to be so awesome when it's finished! It's a lot of work now, but just knowing you can pull it off is going to make you feel just as talented as MB herself!
Is it harder doing all that painting with the tiers already assembled?
I pretty much decorated each of my tiers seperately so I wouldn't have to strain my arm reaching up to paint each tier. I also took the lazy route and colored my RI gold (looked like dark mustard! LOL!) for piping anything to be gold. That way if I missed anything with the luster it would be less noticable (and I wouldn't have to make sure I got into all the cracks/crevices).
I'm a slacker - so if there's a shortcut, I'm gonna find it. LOL!
