I am in need of metal base plates and the corregauted plastic stuff.  These are needed for balloon frames (can't get them at GO and don't have time to go to Up, Up between now and Thursday) and for a balloon sizer.

Never had to look for either before so if anyone can point me in the right direction I would be eternally grateful.

Hi
I don't know about over there, but I have bought corregauted plastic at sign making shops, or hardware store sometimes have it.
