Feel a bit silly asking this as pitched plenty tents in my time although not for a few years and am ex fisherman so liked to think I could suss most rope related stuff out but I can't for the life of me suss these out. It's a DD 3x3 tarp with sliders on the guy lines, so how do I use these to tension the lines? Also does anyone simply peg the loops on the tarp when rigging simple A frame?
