I'm not sure if this has been mentioned, but for prints that have been in a tube for a while, I would take them out of the tube and let them relax for at least a couple days before you weigh them down to flatten.
On the storage topic, does anyone have a link to good/cheap sleeves that are slightly bigger than 18x24 and 24x36?
