it's also called a trucker's hitch, basically just twist the middle of the line to form a loop, then stick a bight through it and tighten. depending on which side your bight comes from, the loop will either cinch down or stay open when you start cranking down. you could also just tie an overhand on a bight instead, the advantage is with the first method, is that it is slippery, you can just pop it out.
also, with a ridgeline, you end up having this loop in the same general area every time, and it can wear the line out. i just found some 1/2" welded steel rings at strapworks. weighs somewhere between 1 and 2 grams, and plenty strong for a tarp. you have to specify the lighter ones, which are not listed on the website.
it's probably not best to crank it down extremely tight(unless you are using a seperate ridgeline). the ridge seam will stretch fairly easily, and you don't want to stretch it too much, which is easy to do with a trucker's hitch.
