paper wallet - security concerns - best way to create one.

I used bitcoinpaperwallet.com because the wallets are much prettier 

While you're at it, print a whole bunch, because they should be used only once.

I used Revlar plastic paper, which is waterproof, and very sturdy. I used a color laser printer because inkjet ink is not waterproof.

I store the wallets in a safe, along with my jewelry and gold.

I used a color laser printer we have at the office, which I know is not the most secure choice because it's on the LAN, but while printing the wallets, I had it off the net, connected to a laptop that was booted from a CD-ROM with a Linux and the web site. After I was done, I power cycled the printer, then put it back on the LAN, and then my coworkers started sending jobs to it, which should erase its memory sufficiently.

I use electrum cold storage now (on a separate machine which stays offline), it is much easier to maintain an electrum wallet then printing and keeping of paper wallets, all you have to do is to make sure to keep back up of your seed/password somewhere safe, so even if for some reason the wallet gets corrupted, all you have to do is just restore another using the seed/password.
