Ellis, thank you for the link. I will copy, to refer back to, the contents of each section. Meanwhile, reading through the items, I am already alerted to some things I should keep in mind as I develop my own portfolio and new working studio space. For example, keeping artwork 6" or more off the floor affects my thinking about shelf storage for finished prints and printing papers. Also the note about smoke/fire alarms. And the reminder about off-location storage/ cloud storage backup. This was a very helpful checklist. Thanks again. --Barbara
