a small collage of photos that I would like to show. Some of my works have effects that the scanner simply does not see. But they are very clearly visible on paper, especially in the sun

I can't recommend a specific manufacturer of shiny paints. I buy them from a private craftsman in my country. She makes really awesome glitter. it seems that I bought up her entire range ahahah :D
but I think it's possible to arrange a purchase. Let me know if you need the master's contacts

I can also sometimes use a holographic transfer gold leaf (2 photos from the bottom left). I have a silver and a gold one. It looks like sheets of foil for creativity. Let me know if anyone needs step-by-step instructions on how to do this :)
