I am in the process of making an UQ from an old rectangular sleeping bag.

With it unzipped and spread out, I measured my desired width, cut it, and stitched the cut side closed.

Then, I used a lanyard cut into 2" segments to use a tabs to run cord through. The tabs or loops are about a foot apart from each other from head to toe.

My questions are:

Should I use paracord starting at the foot and ending at the head? Then, attach shock cord to those ends running up to the hammock suspension, or should I just use a longer piece of shock cord running the full length on each side?

Is 1/8" shock cord strong enough to hold up a sleeping bag?

How much stretch is expected?

Does it loose it's elasticity quickly?

These questions display my ignorance of this cord fairly well, and I'm hoping to get some good feedback on how long you've had shock cord in use, etc.

Thanks
