Making and fitting a picture frame window

Well, half way through working on the kitchen and the boss decided the window isn't big enough so I had go off and make a new one! She decided it would be a 'picture frame' window without any openings because the extra framework blocks out the light! It's best to just do it, peaceful life and all that. I went into quite a bit of detail on this one. Enjoy! I have been posting regular updates on this patreon thing- https://www.patreon.com/newyorkshireworkshop
