How do you attach a tarp to a prussik without hardware?
Edit: I see. You can make a prussic with a nice knot. Then, take the loop end of the chock cord and pass it through loop hanging off the prussic and around the big knot to lock it into place. Mmmmm quite crafty.
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.
