I just got a copy of U2's The Joshua Tree. The vinyl is fine, but apparently the jacket and sleeves got wet, so they are functional but ugly... rippled. Is there anyway to get the ripples out of cardboard? I tried a cool iron... but I didn't want to damage the cardboard. I was thinking of misting the cardboard and then ironing it like a wrinkled pair of pants.
Any ideas? I used to iron $1 bills when I was a kid... loved the crispness of them.
