I don't know how you can do them, but here are some examples

Hi, that is another story or artwork (not the white letters on the black band). I did see the "how to do" some time ago. They print it on paper, fix the front side with dull code and then comes the trick. You put the paper with the face down on the table and start gently rubbing on the backside with a wet finger. If you do it carefully the paper will get thinner and thinner without breaking apart.
I did try that technique this afternoon for my walls. It did not work because the paper will not be perfect flat at the backside. You will not notice it on the structured brick wall but it looks ugly on the flat white wall. But the boarder of the paper did blend better because it is much thinner.
