I was struggling to remove the evidence that the marks from the laser left. Why?
I remember some odd things on old toys I only just realised they might have been from the manufacturing process. Won’t say where they might have been from. (It’s not a toy by the way ) It just occurred to me when I removed steel 2 from my window to sand and temporarily put up the flocking digital water marked model still hangs smaller hoop but stronger for the material.
