opinion wanted on my costco under quilt

[novasquid]

i purchased a costco throw blanket, and used a sewing machine's preset for button holes to create holes where i could put on shock cord for both the suspension and the head/foot cinches. the plan is to use this indoors so it'll get a lot of use/abuse of me getting in and out it. does anyone see any potential problems with using only button holes to suspend the quilt?

where the corners are suspended, i doubled the blanket so that the shock cord for suspension would go through two layers of blanket. to cinch the head and foot ends, i just threaded shock cord through one button hole per square. it's surprisingly warm, and i can immediately feel heat reflected onto my back when i get into the hammock. the coverage is amazing when i toss around in the hammock, and it doesn't slip out from under me at all since i'm using most of the blanket (two squares are folded over on the foot end, and one square is folded over on the head end).

picture of head end is attached, which shows one square folded over.

I don't see any issues with the suspension. Its not like you're going to be supporting a lot of weight and doubling it over was a smart call as extra measures go. Since it's a longer quilt, though, I'd put something along the length of it to give yourself some more support. That way you don't have to crank down on the ends as much to keep good tension.

there is surprisingly very little tension on the shock cord and the corners of the blanket. it just seems everyone creating under quilts with the costco blanket makes them bomb proof with channels and lots of support and stitching involved. i just wasn't sure if my shortcuts were too good to be true and i overlooked something.
