Also, would you recommend a 8x5 over a 9x5? I guess certain dimensions work better than others.
In addition, I need to find a place that sells shock cord by the length.
The loop of cordage used to make the prussik is tied to your tarp with an overhand knot. So, you tie a piece of cordage into a loop using an overhand knot, tie it to the ridgeline with a prussik, then untie the overhand knot and retie it to the tarp. This is the easiest way I have found to "permanently" attach the tarp to the ridgeline via prussiks.
Many of the cottage companies on HF sell shock cord by the foot.
DIY Gear Supply is where I've gotten mine.
