buy 50' at an army surplus store. just be sure it is 550 paracord.buya 18 oz plastic jar of Gatorade powder to store it in. drill a 1/4" hole in the top. when you get to camp dump the cord,fill the jar w/a few rocks then put the end of the cord back thru the top and tie some knot on the end (which is now on the inside side) screw the lid on, arrange your paracord, and Sling It! its a great lil gizmo! God bless...
