You can purchase a "rope marker" from most climbing shops. It's designed just for marking ropes without harming the integrity of the rope. I've also heard of people marking their ropes with Sharpies-plain ole permanent marker.

Many, many questions can be answered by browsing this site.
Here is the FAQ on marking the middle of your rope.
Recently, the UIAA has reported that marking the center of your rope with any kind of marker can increase the risk of the rope cutting over an sharp edge.
See:
UIAA
and
UIAA Journals
You will require a PDF reader like Adobe Acrobat, but the Journals are very informative.
Personally, I like to measure by hand, take both ends in your hand, and release rope by the armful, pulling out a equal amount of each strand.

Weave some contrasting-color thread through the sheath at the middle point.

My friend used some electrical tape to mark the middle. He put it on a couple weeks ago. Its been workin nicly for him, but its definitally a permanit solution. Use a rope marker.

Don't alot of books (falco how to rock climb series) say to use a "Sharpie" marker? Is what the UIAA said true for Sharpie markers? I use them to mark my slings with a little mark, wonder if this could be a bad thing now!

my friend uses a laundry marker for his.
also, my partner uses twine rapped tightly around the rope for about 1"-2" in the center. i forget how exactly it's secured to the rope, but you can prolly find more info on that around.
personally, i have the bi-color rope, and i love it...very nice. well worth the dough.

Why the hell is everyone concerned with marking your rope? Take both ends and pull it till you reach the middle!! How about that!!No controversy there!!

The reason you need the middle of your rope marked is for safety. It helps you move quicker and more efficiently when rapping down a wall with one rope. Also, if you are belaying someone, it helps you realize if your rope is long enough to lower your climber back to your belay.

I find it nice to have the middle marked as well as say 25 ft from the end. That way when belaying when you see or feel (depending how you marked the rope) the mark go by you can let the leader know that the rope is getting short.

Cut you're rope in half. that way it's impossible not to miss the middle

I took unwaxed, unflavored dental floss, tied it on with a clove hitch, wrapped it very tightly for an inch and a half or so, then tied the other end on with a clove hitch. Distinctive white floss on the rope where its fairly smooth as compared to the rest of the sheath.

Arlen and Petsfed have good ideas. If you can find a book on knots that's old enough, you will find how to whip the end of a rope with string. Do that at the center. Or tie several clove hitches in series.
Alcohol, specifically ethanol, can be used as a solvent to dissolve nylon. And many marking pen inks use alcohol as the carrier. So using a marking pen . . . . ?

I whipped mine with dental floss... This is how A4naught showed to do it...
Quote:Whipping is an "old fashion", traditional way of finishing the ends of rope of all kinds (as an alternative to hot knifing or taping, etc. But, in this case, using tooth floss in the same way in the middle is a great, nondestructive, removeable, visual AND tactile way to mark your rope.
I found one site, if you're interested, that shows a diagram that seems pretty understandable:
http://www.mem.govt.nz/memwebsite.nsf/wpg_URL/The-Emergency-Sector-Urban-Search-and-Rescue-General-Rescue-Manual-62-Natural-Fibre-Ropes-Knots?OpenDocument
More comprehensive books of knots/ropework will feature the technique also.
Very durable and doesn't slip. Plus, unlike marker, you can feel it as it runs through your non-braking hand, then also as it passes through your belay device.
And, if it hurts...you're doing something wrong...

I think this is even better than the cat piss idea. It has the added advantage that if you have to chop off a damaged section of your rope, you can remove the middle mark and put a new mark on the new middle.
Does it stick badly in a tuber belay device?

I haven't found it to be much of a problem, although I use a Petzl Reverso and not a Lowe Tuber. Try it out before you leave the ground.

I use a marker and must remark it every 10 uses or so..it seems to me like tape and other things could possible get caught up pulling the rope.

A friend of mine bought two double ropes online, and they were the same color. Doh!
He spent an entire afternoon marking one of the ropes every two feet.
