Paper solves all problems.
My kid likes to dump my wallet out on the floor and rummage through its contents-- good practice for the tween years, I suppose. Problem is, key items from the wallet sometimes end up under the dollhouse in the living room when they should be with me at the grocery check stand.
Thus, in a fit of boredom, I made her a paper wallet today. Try to do that online. Oh, that's right. You can't. Sorry, interweb.
PS: Here is someone elses's design for making a paper wallet-- it looks a little more official than mine. Might give it a try.
Update Here is my attempt.
