that's great!
I was going to do a trifle the other day but didn't have all ingredients and Time.
So I Baked a Yellow cake in 9x13.
1 Pack Vanilla instant pudding + 1 cup of milk:
Folded in 1 container of cool whip
Topped cooled cake with the cream then Sliced berries....
Soooo...
I don't know about them being warped/lopsided ...but I know someone who's stand shattered in transport to a show....all the more reason to use original boxes.
