I was surprised not to be able to find this tie, which to me is the single most fundamental column tie, documented anywhere on the internet or in the books that I own.

You start with a lark's head about the column:

Then reverse directions:

And wrap around to the desired cuff width:

Now if you look back to the beginning, there are two interlocking bights, one in a single line, the other in doubled rope. Pull the working end all the way through the doubled one:

Now reverse directions, and make a loop over the cuff to the opposite side:

And then run the line back under the cuff, and up through the loop:

Then tighten it down:

This is great if you're going to be pulling directly away from the column, or along it in the direction that you passed under the cuff. However, you'll notice that if you pull in the opposite direction, it tends to make the cuff roll over and bunch up:

To avoid this, if you're going to be pulling in that direction, perform...

This is the double column version of the lark's head based single column. It starts the same way:

At this point, instead of hitching off the cuff, wrap all the way around the back of the cuff, going between the columns:

Adjusting the tension on this cinching wrap is what determines the overall snugness of the cuff:

At this point, there are several ways to finish it off. One is to split the lines around the front of the cuff and tie a square knot; that doesn't require much space between the columns, but had the disadvantage of only pulling on the back of the cuff, which can make it feel like it's tightening under tension. An alternate approach is to now hitch off the front of the cuff, similar to the single-column version, by first passing through the starting doubled-rope bight:

Then forming your hitch about the opposite half of the front of the cuff:

This will pull on the front and back of the cuff evenly, which is generally more comfortable. You'll notice,...
