A Bavarian style cushion - made by order

So what should you make if you have such complicated order.
I was asked to sew a cushion cover Bavarian style, traditional German look for a 60 years jubilee.
I had idea to make something like houses with beams. Do you remember the houses in Germany?

Then wanted to make a cushion like a house,...
Then have seen a linen shirt with embroidery and gorgeous buttons on the front.
A brilliant idea crossed my mind.
Cut rectangle, different strips, attached on a piece of batting. Voila...

 What about the back? Do you wander how I have used the buttons?

So did I the cushion.
