What types of things are written on a line cookie?

I drill a set of holes in my cookie for zero vis recognition, in addition to a sharpie marking.

I put a small strip of self-adhesive Velcro tape on mine. Easier than drilling holes. I also write my initials on them.

I think ,most of us would disagree. There is a very very big difference between a personal cookie and an arrow or rem with distance markings. A cookie in a cave that’s not yours should be no different than a rock. Cool to look at but means nothing to you.
There are people, esp those that survey, that do mark their cookies with numbers because they place them in order as part of their work. Most people don’t number their cookies. Making it a 3 digit number imo is worse. Go to Europe and place a cookie with 330 on it in the first 1000 ft and someone will think it’s meters.

Mostly only looked at it to figure out who the heck left their marker in the cave for a long period.

Here’s how I customized my cookies and REMs. I went on a dive with another guy with my initials and we both had white cookies with a notch filed in them. Those stripes are Spurs colors, BTW.

If someone is looking at a cookie and interpreting anything from my scribbles that's a really big mistake. Cookies and REMs (should) have zero meaning to anyone but the owner and buddies.

I write my initials, and I number them. Helps me keep track of navigational cues.
