I'm really daft about ball marking, but I just love the ritual of sitting down with a brand new dozen, unpacking them all, and marking them all up in a very specific way. Previously, I've been marking the 1's with 1 dot, the 2's with 2 dots, and likewise the 3's and 4's. Different colours for each number, and 6 marks per ball.
For my last box though, I've changed my ritual, and am now doing 2 colours, 2 dots, 6 sets per ball. So I'll pick 2 colour pens (different colour pairs per number), say red and black for 1's, blue and orange for 2's, etc, then do a pair of dots, one red, one black, in 6 positions per ball. This is so that there is always one position which is visible on the top of the ball, even if plugged.
Wow, it actually reads crazier than it actually is. I won't tell you about the chanting I do while marking
Anyone know a good OCD consultant/psychiatrist (delete as appropriate)?
