Fondant and gumpaste masks

I am working on the decorations for the masquerade cake.  I wish I could say I have a definite plan.  It will be a 3 or 4 tier cake.  The birthday girl requested a square cake.  I'm thinking of mixing up the shapes and make a square bottom tier, a round tier and then another square with a round top tier.  I made masks to go around the bottom tier.  I used a bat cookie cutter and cut out the eye holes.  I placed them on straws to get some dimension for the nose part.  I think they are looking ok.  I'm hoping to spray them silver.  More to follow.  Oh, I used my pasta maker to roll the fondant.  It worked out very well.  I wanted a consistent thickness of the masks, so that was the best tool I could use, and also, it was easier on the wrists, no rolling!
