Just for my understanding:
I also had the private key copied 5K9bNHVjCGgqnv1GZAKaye4VPdFUMvexbqCCmkB5rouC93wWSC
When going to Blcokchain.info. opening an account/wallet and importing private key, I get the Error Importing private key: unknown key format.
I also tried to use a new multibit wallet, but even when exporting a key, replacing it with the one above and reimporting, it did not work.
So how would I recreate my wallet from just a private key backup?

Seems I was too slow

Privkey: 5K9bNHVjCGgqnv1vGZAKaye4VPdFUMvexbqCCmkB5rouC93wWSC
The 0.1BTC are already gone
The idea isn't bad. I think I saw some other threat here with a similar approach (the banknote one iirc).
That one worked without folding by using those grey rub-off stickers.

I've also made some nifty paper wallets (though not as well designed as yours), but here's my problem with making well designed paper wallets:
If you're making it for yourself, what do you care about design/tamper-proof/etc?
If you're making it for others, why would they trust you that you didn't print another copy of the private key at home?

Looks like someone already nicked the 0.1. 
The paper wallet looks great. The old one on bitaddress.org is too low resolution for printing, plus the private key is right there in the open necessitating that each bill is put into an envelope for security. Your bill solves those problems beautifully.
Where did you buy the tamper proof tape?

I had lots of fun this weekend working on my own design for a two-sided tri-fold tamper-resistant paper Bitcoin wallet. Thanks for any and ALL criticism / comments -- whether it's about the look & feel, functionality, security features, etc. See:
http://youtu.be/V4H1VE3EAtI
This video is also a treasure hunt in which I happily invite you to “steal” 0.1 BTC . Finders keepers, so race on!
Design features:
When I’ve got enough feedback and a final design, I’ll publish a web page that will generate these wallets with just a couple of clicks. (No photoshop required, as the foundation will be based on the excellent wallet generator at bitaddress.org which as you probably already know uses a secure javascript page you can run even while offline.)
If you'd like to print out a sample for yourself, see PDF links here: http://cantonbecker.com/projects/2013/bitcoin-paper-wallet-design-video/.

Design features:
- Private key is hidden behind folds, so your wallet content is still safe if left out in the open or photographed.
- Tamper-proof tape indicates when you (or someone else!) has revealed the private key.
- Folding design obfuscates private keys so they’re hidden even when holding wallet up to a bright light.
- Reverse side has basic wallet operation instructions and a register for writing down deposits / balance.
- Private and public keys are replicated (and rotated) in triplicate to maximize chances of recovering keys if paper is damaged / crumpled.
