I often use a 6" or 12" ruler. I like the hook rules the best.
They are flat, but shiny, so I can usually see where I left them. That is until a fine coating of dust settles. Then they are almost un-seeable to my aging eyes.
I've purchased brightly colored ear protection, tape measures, marking knives, etc. I was looking at brightly colored rulers, but I read that they are made of aluminum, and their thickness makes it hard to transfer the marks to the wood.
Any thoughts? Any recommendations?
