Reconstructing an image from overlapping parts

[Krikor]

One thing led to another...

In order to reproduce the steps of this tutorial but without having an image at hand (for instance, multiple screenshots of something too big to fit on a screen, etc), I decided to intentionally misalign an image.

In this game I ended up discovering how to create interesting aspects of sketches.

Duplicate the original layer;
Rotate the new layer by 0.60 (with rotate tool); OR (I found out later, move with the Move tool about 6 spaces to one side)
Change this layer's mode to Difference;
Making new of the visible;
On this new layer (Visible):
a- Invert the color - Colors - Invert;
b- Colors - Levels - Low Input - 230 (I used 230, but this value must be adjusted depending on the image used);
c- Colors - Desaturate - Desaturate.

I discovered that, unlike the Move tool, with the rotate tool, it is not possible to preview the correctness of the layers.

Ofnuts, thanks for the tutorial and for indirectly helping me figure out how to create interesting sketch looks.
