How to organize a relatively large Flask application?

Flask 0.7 implements Blueprints. They are great for using the route decorator without importing the main application object.

I have created a Flask boilerplate project called "Fbone", please feel free to check it out and fork :)

Fbone (Flask bone) is a Flask (Python microframework) template/bootstrap/boilerplate application.

Overview

• Well designed for big project using blueprint.
• Integrate with hottest frontend framework: jQuery / html5boilerplate / bootstrap.
• Backed by the famous SQLalchemy.
• Implement tricky "remember me" by flask-login.
• Handle web forms by flask-wtform.
• Unit testing with flask-testing and nose.
• Easily deploy via fabric and mod_wsgi (example included).
• i18n by flask-babel

btw, I just found this wiki on building a large project with Flask useful, pls check it!
