This time it was Yellow time! After I did yellow, I didn't put everything together, I decided I would quickly start with the last real color, red.
So I started that in September 2019 And finished around Januari 2020.
It's the Start of March now and I decided to slowly start with the border.
Now I think my approach to that border will be a little different than with the colors.
Now I have to work with all 32 pictures.
I'mdoing the white-Black first.
This is the plan:
I noticed with the "special pieces that it's quite easy to see the same piece over and over again, so I sorted them that way.
(although it takes a lot of time!)

I also numbered the lines of pieces, what I mean by that is I took image nr1 as reference and the border of the color are the lines 0. If I have an image with more lines they are +1 or m+2 andif they are less it's -1 or even -2.
So in principle If I have all the pieces sorted by identical and I know where they go I can just put them in their place, I just don't know on what image they go.
So after a while I gave up on having the line perfectly aligned, because I was going CRAZY! I kept on shuffling them around and never got ALL of them perfect.
One of the reasons why I gave up is because as soon as the puzzle is completely made I'm tossing it.
I'm pretty sure I'm already missing a piece (completely yellow) and I don't have a wall long enough to hang it anyway.
So by June all the black white borders were done.
I'm leaving all the boards on my table so I can finish it as soon as possible!
