Paper wallets are not a good idea. When starting out you should use a desktop wallet for larger amounts. Later on you can use offline wallets from armory or electrum. But with paper wallets you will have to worry about change, sweeping vs. import, securing the private key etc. Paper wallets are easy to get started with but hard to spend from securely.
I have no idea, what you are talking about. What is change, sweeping vs. import, etc?
I thought, if the wallet was created securely, it is offline. So nobody can get to it.
Now, you have me totally confused.
