Thanks for all the advice guys!

Do you bury the flower nail? It wouldn't be long enough to poke all the way through....? Do you lower the oven temp? Do you torte it and add support in the middle?
For the chips (I want them to look random and un-uniform like Lay's...not all the same like pringles) I'm going to use SI ivory and gumpaste for the base color, cut them with an oval cutter and re-shape some of the edges so that they're random in shape but similar in size. I'm going to dry some in the Wilton lg flower former, and dry some in weird contortions. Then I'm going to get one of those nifty preval sprayers and spray them with a very light base coat of yellow and just a spritz of brown. Maybe a little granulated sugar on top for salt? Salt is her weakness....

Ya think it'll work? I dunno, I guess we'll find out! I think we're going there on the weekend of the 28th. I'll be sure to post pix when I'm done.
