Ah yeah. Well potentially you can go without the linelocs at all; this is what I normally do, as for one it's a bit lighter (and less bits is typically more reliable), but mostly because I haven't figured out an easy way to make them attachable and detachable (and I dont' want them sewn onto the tabs, as the ones at the head end in particular would be very uncomfortable.
Thus, normally I run the shock cord through the corner tabs on the quilt (and sometimes through one of the tabs near the middle if I want it suspended a little higher, and then tie a loop near each end of the cord. Then, using a mini carabiner or one of those plastic mitten hooks, I'll just clip through those loops up to the ridge line of the hammock, just past the gathered end. It's a bit fussy since you'll have to tie the loops in about the right distance from the quilt so that it positions about where you want it (if you know one of the slideable loop knots it's probably pretty easy, but I've never been good with knots).
If you can figure out an easy way to attach/detach those line locs to the tabs on the quilt (I haven't yet, though I haven't put a lot of time into it) then that makes adjusting the position of the quilt way easier, and it can be moved then at any point after its suspended. When attached to the quilt, the cord would run out from the corner tab, up through the bottom of the lock, then down through the top, with the mitten hook or carabiner placed on the cord between the corner tab and where it feeds up into the lock.
Hopefully that all makes sense. I'm a very visual learner, so I find it a little tricky to explain through something like this.
