I'm discovering first-hand what a pain the 9' rolls of Savage paper can be after bringing them home to discover I have 8' ceilings. Can anyone tell me if there will be any adverse effects if I store the rolls upright in an unheated garage? Also, I know that storing the rolls flat will ruin them by creating ripples, but has anyone used/created a rack system for storing them horizontally on the wall using a rod/rack system? Would this work?
