Thank you very much @mandragora88! I tried my best, but this was just a practice, to see how the glue, coffee and this paper acts when used together. Now I know.

There's a guy here at HIVE who paints with coffee. I usually vote for him!

Can you link me his profile to check it out please?

But it can get a bit boring not to develop, doing the same thing over and over again!

We agree on that. But you know how it is, each to their own.
