I scavenged a piece the company's old mission 
statement was on and I'm quite hard pressed to 
bend it (around 20x26" by my guess, so it would 
be even harder to bend after I pressed it down)  
Think that would work?

I actually found a box  earlier for oversized 
printing sheets that looked perfect, but it was 
an inch too narrow  *mutter mutter*

Maybe I should stop being so neurotic about 
packaging ^_^
