Yeah, I thought about doing a zipper, but I think i'm going to stick with my snaps for now. I've already got all my stuff (shock cord, cord, mini 2 hole cord locks, snaps, grosgrain, 1/2" elastic for pad strapping system, etc) and fabric/Insulation cut out.
For straps, i'm using 1/2" super low profile plastic center release watch buckles. Female ends are going to be attached to quilt with grosgrain and the ladder lock male ends are going to point out from each other on 1/2" elastic wrapped around the pad. That way, I can tighten or loosen the quilt around me and above the pad, but it won't shift with me when I toss and turn, as I toss and turn a lot.
It'll be like the way the Katabatic quilts attach and can be tightened. Got the idea and tutorial from Amy L's double quilt attachment post:
except mine will use elastic so it'll have some give (i could have put the elastic on the quilt side, and use grosgrain around the pad... but i didn't think of that until after I already ordered everything, but i'm still happy).

I put some tiny pieces of 3M reflective tape on the buckles so i can see it better at night/low light.
