Make Paper Wallets to Keep Your Bitcoin Addresses Safe.
For long-term storage of bitcoins (or giving as gifts) it's not safe to store your bitcoins in an exchange or online wallet. These types of sites are regularly hacked. Even keeping a live wallet on your own computer can be risky.
Your Keys, Your Bitcoin.
By printing out your own tamper-resistant bitcoin wallets and generating your own addresses, you can minimize your exposure to hackers as well as untrustworthy people in your home or office. Just transfer your bitcoins into your new wallets, and use common sense to keep your wallets safe the way you would jewels and ordinary cash. Or give them away!
Safer than Hardware Wallets
Although hardware wallets can be secure, they still have their faults. Many hardware wallets running closed-source software leave your seed phrase and private keys vulnerable to theft. Paper wallets give you direct control over your Bitcoin without a third party.

Why trust this site?
This generator is based on a well established and most trustworthy open-source engine for generating addresses using your own browser's JavaScript engine. No crypto-code is run on this web server, and no addresses are transmitted over the Internet. BIP-38 encryption is fully supported as well. If you don't trust this service (or pseudorandom number generators in general) this wallet service lets you roll dice, shuffle cards, or supply your own "vanity keys". To be more secure, you should download this wallet generator from your browser and run it offline.

Wallets come in 12 different languages, as well as special Christmas and "red envelope" / Chinese New Year designs.
Here's a PDF template for making an envelope for giving away Bitcoin for the holidays.
1. Tri-Fold Template
This bitcoin key generator guides you to print both a front side and a back side for your paper wallet. All sensitive details on the front side (the private key and QR code) are folded up and securely taped shut so as to stay hidden. For additional security, you can seal your wallets with the tamper-evident serialized hologram stickers available for purchase on this site—though any sufficiently opaque (light-blocking) tape will work fine.
2. Tamper Resistant
One risk with a paper wallet is that someone with physical access to your wallet may "sneak a peek" at the private key and withdraw your funds without your knowledge. This wallet's folding design and obfuscating security patterns resist "candling" -- the process of shining a bright light through the paper to reveal what's printed inside. Serialized tamper-evident hologram stickers destory themselves when removed, preventing stickers from being replaced with new ones.
3. Perfect for Giving
Want to give bitcoins to someone who isn't tech-savvy? Need to send bitcoins by mail? Use a pre-loaded paper wallet. The sealed-shut folded design helps to ensure that the recipient won't accidentally reveal the private key. For recipients unfamiliar with bitcoin, the reverse side of the wallet has printed instructions for checking the wallet balance and withdrawing funds.
The biggest threat to your wallet isn't an evil WiFi packet-sniffing robot. Your worst enemy is 
The private key on this wallet is recorded in typical "Wallet Import Format" (WIF).

The problem with printing out secure documents—even if your computer is 100% virus/trojan free—is
that your printer driver and/or operating system may be keeping copies of the documents you print in
some sort of "spool" or print queue. If a hacker or virus gets into your computer and knows to look for
these cache files, then they can get your private keys and "sweep" your wallets. Here are some tips on 
If you've got loads of applications on your computer, or if you use your computer for "risky behavior"
(like installing freeware or visiting java / flash websites)
consider dedicating a computer (or at least a bootable partition / thumbdrive / "live CD") for paper wallet
printing. Never take that install online. Transfer the wallet generator website files to your clean OS using
a thumbdrive or other non-networked method.
Some advanced printers have internal storage (even hard drives) that preserve copies of printouts. This is a risk if someone gets access to your printer,
or if you dispose of your printer. There is also the possibility that a smart enough printer can be hacked.
This isn't quite tinfoil-hat level paranoia, as we've seen examples
