SR - This is great stuff. May I ask...for the tarp you made, what would the approximate cost of the Cuben have been...?
On tie outs...it would be great if a no-sew solution could be had here. What if someone used a braided dyneema cord, same approximate length as the paracord you used. And unravel this cord at the ends so it spreads out thin and wide for the last inch or so...I wonder if that could be successfully glued to the Cuben and then sandwiched as you did...strong enough to hold the forces involved with a tie out point...
