I am making a canned sign and the front is 3/16" translucent white lexan i got from a sign supplier..off a roll...well its curled...like a bananna. which sided do i cut out? how do i get it flattened? what should i do? the sign face i am cutting is 32 x 72. Also...inside the sign which is LED lit...should I put supports for the face to keep it in place if it is pemanently bananna-ed? thanks for any help. Joe
