You won't go far wrong starting with a free model from Canon.

There are lots to chose from with varying levels of complexity and you can just keep printing pages as you make mistakes and learn.
I've seen a fairly simple looking viking ship on there that might be a good starter for you?
Like you, I'm a fairly experienced modeller, however I've only started paper modelling in the last couple of years.
It's like starting again! It's good fun though.
