what's the one item you'd tell them they needed? (besides software)

This question was posted on the Scrapbooks Etc Facebook page. All the answers refer to paper scrapping items. What's the digi version of this list? Forget about specific kits, what's one digi item you couldn't do without.

We are so lucky we don't need paper trimmers, scissors, glue, etc!

I think I would say a good basic cardstock pack, with blacks, whites, and kraft papers.
