Rope middle mark with dental floss

Don't melt your rope sheath.... unless you are doing a really long rap with a hot belay device.

You obviously bought the wrong rope. I own a yellow Sterling Biathalon. The pattern change is so obvious it looks like two different ropes.

There are numerous other advantages of bipattern over a middle marker that help in rope management. I will never buy another trad rope that isn't bipattern.

Some bicolour though is hilariour. A friend bough a rope from the czech company making "Tendon" ropes which had one thread change of red an green to just green. (Pity, I'm red-green colour blind!)

The UIAA warns against using Sharpies or similar markers to mark the middle of your rope but it looks like the jury is still out on it.

The problem is that you're never "done with it" after using a Sharpie. They need constant re-applications, IME.
