Hello, Ann
Nowadays, this kind of thing is produced using a screen printing process. Back in the sixties, something like this was made simpler. The cord technique creates such an effect. There are two ways. Printing or spraying. Both require a lot of experience and you should go to a painter for this, or make enough attempts on other objects before you go to the billiards with it. I have photographed the two possibilities here, they are not perfect, but show how it works. A skilled painter masters this job.
