Litecoin wallet help

I’m having a bit of trouble with litecoin and am hoping I can get a little help!

I bought bitcoin through coinbase.com. I then transferred it to btc-e.com so i could convert the bitcoin to litecoin.

Once I had litecoin on btw-e.com, I created a paper wallet on liteaddress.org and put all of the litecoin there.

Here is where I am having trouble. How do I get the litecoin out of my paper wallet? I’d like to trade it back to bitcoin, but I need to be able to get it out of the paper wallet.
