Pattern mayhem!

During the weekend I mostly worked on Image 3 and  sorted and laid out all the special full Orange pieces.

Today I'm finally sure of the pattern. 

In the blog of November 11th 2014 I talk about finding a part of the pattern. The rest I would know once I was done with all the pink. 

Well, I figured it out today (or at least I think so). 

In November this is wat I figured out: 

"For now this is my conclusion:

Image 2, 6, 10, 14, 18, 22, 26 and 30 have the same cutting pattern

Image 3, 7, 11, 15, 19, 23, 27 and 31 have the same cutting pattern too, but turned 180 degrees."

So this is how I visualised it: 

The blue arrows point what way the pattern goes.

Then I found a second pattern on some Images and this one turned 180 degrees in some Images too. So Image 13 was pointing down, 12 up, 21 down and 29 down.  

At that point I assumed:

Blue Pattern:

Image 2,6,10,14,18, 22, 26 and 30

Blue Pattern turned 180 degrees:

Image 3, 7, 11, 15, 19, 23, 27 and 31

Red Pattern:

Image 4, 8, 12, 16, 120, 24, 28 and 32

Red Pattern turned 180 degrees:

Image 1, 5, 9, 13, 17, 21, 25 and 29.

Like this: 

Looked nice and simple, but then! Mayhem

I found this: Image 5 and 21 had the Blue pattern pointing up! 

Now how could I miss this before? Well the patterns don't always match up in the corner of the Image. They shift 1 or 2 rows up or down. 

So now the pattern is even simpler: 

But the puzzling so much more annoying, because that means even more exactly the same shaped pieces. 

This results in this piles like these: 

But still, it's progress. 

And while I was going through all the Images, I found Image 21 again, where I still had a lot of Black-Orange pieces to putdown. So that's what I did today. 

I need to hurry up if I want to be finished by Christmas!
