a good place to start

Skimming thru the posts, usually you get a question on where to start beginners on paper models. This is a good one, and then advance with other very simple shaped dinos on papermau.
Unless you plan to hang out with the beginner and help them step by step, a few pieces a day, I wouldn't give them something very difficult.
