Hi again...
I thought it would be nice, to see my last findings of 7-Layers all together in comparsion with backlight, to view the various colors of the first and third translucent layer. So here is the result....I am sorry about the bad quality of some pictures, I just ordered a new camera with 1cm macro, this will work better for small objects, but I couldn´t wait....

I have had my problems with that backlight and so the colors of the first of each row is more light blue, not clear...(I would pull off my hat, if I had one, for all those, who show us all these beautiful and high-quality pictures here!!!)...there is some pink plasticine inside the perforations to keep the light out...

The third one top row is in an unusual shape, I would say „cornerless cube“, and I wonder, if it is like that from the beginning or if it has been done later from a rectangular shape...??

Perforations from <1mm to 4.5mm...two with lightly twisted stripes, some with pointed stars, others with rounded stars, and no stars at the 6th layer from the last one in second row....
Hope, you will enjoy....
